Exposure to ionizing radiation by service personnel working with cyclotrons used to produce radiopharmaceuticals in PET diagnostics.

Objectives: While working with cyclotrons used for the production of radiopharmaceuticals, workers can experience significant exposure to the adverse effects of ionizing radiation. The aim of this paper was to determine the typical level of such exposure received by such personnel while servicing cyclotrons.

Material And Methods: Exposure was assessed using TLD detectors placed in an anthropomorphic phantom, as well as dose meter to determine whole body and eye lens exposure.

Using Monte Carlo methods for H(0.07) values assessment during the handling of F-FDG.

The dose limit for the skin of the hand is typically converted to a surface of 1 cm, which means that one needs to measure point doses in different places on the hand. However, the commonly used method of measuring doses on the hand, i.e.

The photo-transferred thermoluminescence phenomenon in case of emergency dose assessment.

A major disadvantage of dose reconstruction by means of thermoluminescence (TL) is the fact that during readout of any TL material exposed to ionizing radiation (i.e., during measuring the glow curve), the radiation-induced signal gets lost.

THE STRUCTURE OF Hp(0.07) VALUES OBTAINED BY THE NUCLEAR MEDICINE PERSONNEL DURING 18F-FDG PRODUCTION AND INJECTION.

The production of 18F-FDG is a multi-stage process, which includes not only obtaining the marker and labelling the radiopharmaceutical but also carrying out the quality control of the obtained compound. The staff can be exposed to ionizing radiation at any stage of production. This article presents the results of hands exposure of staff members employed in a facility, where 18F-FDG is produced and injected into patients.

MTS-6 detectors calibration by using Pu-Be neutron source.

Background: Thermoluminescent detectors, type MTS-6, containing isotope Li (lithium) are sensitive in the range of thermal neutron energy; the Pu-Be (plutonium-and-beryllium) source emits neutrons in the energy range from 1 to 11 MeV. These seemingly contradictory elements may be combined by using the paraffin moderator, a determined density of thermal neutrons in the paraffin block and a conversion coefficient neutron flux to kerma, not forgetting the simultaneous registration of the photon radiation inseparable from the companion neutron radiation. The main aim of this work is to present the idea of calibration of thermoluminescent detectors that consist of a Li isotope, by using Pu-Be neutron radiation source.

Hand exposure of workers in F-FDG production centre.

F-FDG is the most popular radiopharmaceutical used, among others, in oncological diagnostics by PET technique. The production of F-FDG is a multistep process that begins by obtaining the radioisotope F, and subsequently labelling the radiopharmaceutical, as well as quality control of the resulting compound. In each of these stages, the employee has contact with ionizing radiation.
