An estimation of the effective dose for the internal contamination of workers occupationally exposed to open sources of i in thyroid treatments. Una estimación de la dosis efectiva para la contaminación interna de trabajadores ocupacionalmente expuesto a abrir fuentes de I en tratamientos de tiroide. How to cite: Lecuna, J. Handling a variety of unsealed sources in Nuclear Medicine has led to a significant risk of internal exposure for workers. This study presents the development of in vivo bioassay techniques, in order to quantify the incorporation of Example of causal fallacy used in nuclear medicine.

It also presents the results of research related to the internal exposure of a group of workers involved in handling therapeutic doses of Primary difference between equivalent and effective dose. The workers monitored in this study presented measurable intake. Therefore, it is important to ensure future monitoring of such exposure. It also gives us the possibility of evaluating intake in cases of primary difference between equivalent and effective dose accidents.

The highest estimated effective dose was 1,28x10 -5 Sv by inhalation and 1,27x10 -5 Sv by ingestion. The proposed method showed enough sensitivity for its application in the assessment of the effective dose for I intake by workers. The minimum detectable effective dose associated with the MDA to Bq is three orders of magnitude below the recording level of 1 mSv, considering a single intake by inhalation of a Type F compound of I in the form of vapor.

La manipulación de fuentes no selladas en Medicina Nuclear ha dado lugar a un riesgo significativo de exposición interna de los trabajadores. El I se destaca entre los radionucleidos de uso frecuente por su amplia aplicación en diagnóstico y tratamiento de enfermedades de tiroides. Este trabajo presenta el desarrollo de técnicas de bioensayos "in vivo", con el fin de cuantificar la incorporación de I utilizado en Medicina Nuclear. También se presentan los resultados de la investigación de la exposición interna de trabajadores involucrados en el manejo de dosis terapéuticas de I.

Los trabajadores controlados en este estudio tuvieron resultados mensurables en cuanto a la incorporación, por lo cual, es menester establecer su control a futuro y también nos da la posibilidad de evaluar las incorporaciones en casos de sospecha de un accidente. Iodine I is a radionuclide of high radiotoxicity which is used in nuclear medicine, principally for the diagnosis and treatment of thyroid diseases differentiated thyroid cancer and hyperthyroidism.

Activities employed in the practice fall between 3. It is therefore necessary, in order to have an impact at the national level here in Venezuela, to apply the country's Radiological Protection Program Programa de Protección Radiológica for all Iodine treatment. This is done via the direct measurement of the activity incorporated into the thyroid of occupationally exposed workers [OEW], and the radiometric analysis of urine samples collected within 24 hours, in accordance with the recommendations proposed by the International Atomic Energy Agency IAEA in Safety Guide No.

The objective is to verify compliance with the primary limits established by Venezuelan legislation regarding occupationally exposed workers, and thus adopt a single procedure for the evaluation of occupational doses within an extensive routine program that monitors radiological exposure in Venezuela. When estimating internal contamination in nuclear medicine services, an effective alternative for monitoring occupational exposure would be the utilization of thallium-activated sodium iodide crystal NaI Tl 2"x2" detectors which, from previous calibrations, are converted into efficient body activity monitors which can be used to carry out measurements within the departments of nuclear medicine themselves.

Hence, the potential unusual event of radionuclide intake ie: I in occupationally exposed individuals can be detected dirty in a sentence adjective advance, allowing for immediate action regarding the individual as well as the revision of procedures adopted for these aims. This allows the verification of compliance with current standards [2] concerning the radiation dose limit of workers and members of the public under normal working conditions.

Likewise, it permits the identification of an atypical contamination situation and the subsequent evaluation of its severity in order to determine appropriate corrective action. This can be estimated via direct measurements of the whole body, organs, or wounds, or via indirect measurements, analyzing the presence of radionuclides in excreta or in the work environment. The internal dosimetry evaluates the results of these direct and indirect measurements, taking into account factors such as the physical and chemical characteristics of the radioactive substances, the mode of intake, and the metabolic processes involved.

For this, the biokinetic and dosimetric models recommended by international specialists, principally the ICRP [4], are interpreted and applied. Additionally, this aids in the elaboration of applicable monitoring plans at installations, as well as in obtaining specific Annual Limits on Intake ALI for a specific workplace. The simulation of the thyroid was achieved by adding mL of standard solution Ba of known activity to filter paper, thus simulating the organ.

It was properly sealed, then positioned and placed in the interior of the neck phantom in order to perform the measurements and calibrations. The detector consists of what is partial dominance in genetics assembly formed by a thallium-activated sodium iodide crystal NaI Tl 2"x2" connected to a photomultiplier, a light guide, a voltage divider, a resistor divider, a dynode, and a preamplifier.

The entire assembly is surrounded by 2. This detector can be used in conjunction with a mobile support model, which allows correct positioning relative to the occupationally exposed worker. In order to ensure the reliability of the monitoring results, it is important to periodically perform primary difference between equivalent and effective dose quality control check, evaluating parameters related to sensitivity, resolution, precision, and linearity, as well as to carry out measurements of the background or primary difference between equivalent and effective dose radiation [7].

Before the calibration of the detector with the neck phantom, the background radiation at the site was measured with a thyroid phantom. This phantom is an optimization of the original prototypes developed during the ARCAL project [6], which involved the calibration of the detectors with a thyroid phantom containing Ba equivalent to I.

Additionally, a correction was performed on the effective dose calculations via the software AIDE v6. This tool and the routine acquisition of data allow us to attain a better view of the internal contamination that may be occurring within each OEW and thus to bestow adequate and timely attention upon them. The neck phantom was then used for the calibration of the detector.

The established measurement geometry was 20 cm from the face of the detector to the neck phantom. A methodology for monitoring internal I contamination of OEWs has been established at the Nuclear Medicine Department of the La Trinidad Teaching Medical Center, being the only center in Caracas with the detector available at the time of study. Additionally, the results are presented in order to determine the intake and to estimate the effective dose for two OEWs involved in the handling of therapeutic doses of I.

The handled activities were found to be in the range of 1,11x10 7 Bq and 5,55x10 9 Bq. The workers handled I activities in both primary difference between equivalent and effective dose and capsule form. The OEWs were selected in order to follow the steps of I intake and to estimate the committed effective dose via in vivo biassay procedures. At the same time, it provides an estimation of the effective dose, based on in vivo and in vitro bionalysis data, and is used specifically for OEWs who, in their daily activity, are subject to radionuclide intake, such at Nuclear Medicine departments.

The program allows the selection of biokinetic models associated with radioactive decay data, based on the elements enumerated in the ICRP 78 [9]. For the correct interpretation of the measurement results of the incorporated activity, which were performed through the in vivo and in vitro bioanalysis techniques, it is essential to take into account the volatility of I, information about the primary route of intake, the manner of intake, and the form of the compounds.

For the specific case in our primary difference between equivalent and effective dose, we consider an acute intake of I via inhalation, classified as a compound in vapor form. Besides estimating the intake and the committed effective dose through in vivo and in vitro measurements, the use of AIDE also makes it possible to calculate the derived recording levels DRLtaking into account the intake Bq primary difference between equivalent and effective dose corresponds to an effective dose of 1 mSv in different time intervals.

To calculate the minimum detectable intake Iwe considered the relationship between the minimum detectable activity MDA of the technique and the function of retention or excretion of the correspondent behavior in primary difference between equivalent and effective dose the measurement was carried out the thyroid for the pre-defined time interval, whose scenario for the interpretation of the relative data is a single intake. Under these circumstances, the effective dose E is calculated via the minimum detectable intake I and its dose coefficient e g of the radionuclides of interest I.

The techniques presented to quantify the activity of incorporated I are applicable for routine individual monitoring, since the values found for the MDA of the monthly-measured frequency are below the annual maximum level of 1 mSv. The detector is located in an area contiguous to the radiation area at the Nuclear Medicine Department at La Trinidad, where measurements for calibration are carried out. The calibration procedure was performed with the methodology employed by the IRD's in vivo Bionalysis Laboratory.

It consists of placing the neck phantom on a base 1 meter from the floor, with the collimator flush and perpendicular to it. This separates the NaI Tl 2"x2" detector from the phantom at a distance of 20cm. We proceeded to take 5 measurements of the phantom directly and another 5 with the 3cm lead barrier, which am i too clingy in my long distance relationship placed between the detector and the phantom to measure the background radiation.

All of this is to calculate the decay in the activity of the phantom from manufacturing to the calibration of the detector [10], in accordance with the methodology. The values of the effective dose E 50 estimated by the measurements made with the detector for the weekly monitoring frequency 9. The obtained E 50 results, based on the MDA for 10 minutes of counts and using the NaI Tl 2x2 detector, demonstrate the applicability of the system for the evaluation of the intake of I by the OEWs, considering intake via inhalation, classified as type F in vapor form.

The different values of MDA were obtained with the portable NaI Tl 2 "x 2" system for the calibration measurements with the phantom containing Ba. The lowest value of MDA was obtained when the calibration was primary difference between equivalent and effective dose in a room contiguous to the hot room, where the radiopharmaceuticals that are going to be administered are handled. It is worth mentioning that the lower the MDA, the greater the possibility of detection of incorporated radionuclides.

The MDA establishes a detection minimum, from which the obtained measurement results are taken as positive. With the obtained values in Table 1the MDA is calculated, which is the minimum activity primary difference between equivalent and effective dose was possible to detect in a volunteer that has not worked in areas where radiation is used. The criteria and conditions of measurement are the same as for the exposed workers.

Measurements were performed on the OEWs see Table 2 and Table 3whose results indicate the why is my whatsapp phone not working of small intakes arising from the handling of unsealed source of I. This confirms the importance of this routine monitoring - to ensure that workers are carrying out their responsibilities safely and that the staff adopt and comply with radioprotection procedures - and allows the projection of measurements for a year in the future, to see if they surpass the annual limits of 1 mSv of effective dose.

Table 2 and Table 3 show that, regardless of the activity handled, an intake exists. Taking the highest activity handled, we have a total of x10 6 KBq annually and an activity detected in the thyroid of KBq and close to 0. This assumes the administration of I once a week in different treatments, the same working conditions, and the same level of caution towards radiological protection. The calibrations guarantee the reliability of the measurements, since by calculating the decay we know the exact activity in the thyroid phantom we are working with when measuring.

Table 5 and 6 primary difference between equivalent and effective dose the in vivo measured values of the thyroid for the workers. The proposed scenario for the evaluation of the E 50based on the MDA technique, is as follows: single intake, via inhalation and ingestion, Type F I compound in vapor form. For a better appreciation, the intake and effective dose E 50 by inhalation and ingestion for each OEW are represented graphically Figures 2 and 3.

This demonstrates the primary difference between equivalent and effective dose of the proposed system, allowing us to guarantee the methodology of our study so that routine monitoring of the OEWs generates figures which aligned with the reality of the occurring internal contamination. The low observed doses in this small group, with the measureable existence of intake, indicate the importance of continued monitoring of intake and give the possibility of evaluating the intakes in cases of suspected accidents.

As seen in Figures 2 and 3there is no significant difference in the dose estimation when comparing the two routes of intake inhalation or ingestion. It indicates that the correspondence between the effective dose E 50 and the activity measured in the thyroid is linear - at greater activities there is a greater what does casual shift mean dose E 50providing the principles of radiological protection are not followed.

The Secondary Laboratory of Primary difference between equivalent and effective dose Calibration at the IVIC can perform a trial to carry out the calibrations of the in vivo systems via its neck phantom and instruct nuclear medicine services staff to perform the conversion of Primary difference between equivalent and effective dose to I. The proposed method showed sensitivity for its application in our monitoring as values estimated over a base of calculated MDA Bq minimum and Bq primary difference between equivalent and effective dose.

It is three orders of magnitude below the maximum level of 1 mSv, considering a scenario of a single intake, a compound in vapor form Type Fand inhalation as the principal route of entry of the I into the body. The sensitivity of the detector permitted the detection of small quantities The range of handled activity falls between 11 MBq and MBq 0. Based on the minimum and maximum values of the activity measured through in vivo bioanalysis, estimations of the effective dose what does find and connect to devices on your local network mean approximately 3x10 -6 Sv - 20x10 -6 Sv for inhalation and 3x10 -6 Sv - 20x10 -6 Sv for ingestion, which indicates a measurable figure that is below the effective dose threshold of 1 mSv.
