The Program of protection against ionizing radiation, as a part of the Law on Radiation and Nuclear Safety and Security of the Republic of Serbia, prescribes the obligation to establish individual monitoring of exposed workers. In the Radiation Facility for Industrial Sterilization of the Vinca Institute of Nuclear Sciences (Belgrade-Serbia), TLD dosimeters are used for this purpose. Based on...
The Paul Scherrer Institute (PSI) consists of a wide range of different facilities such as accelerator facilities, nuclear facilities and radioactive waste treatment. At PSI East site, the facility Hotlab and the Centre for Radiopharmaceutical Sciences are situated where on the one hand highly activated samples are investigated and on the other hand short-lived radionuclides for medical...
In THAILAND, radioactive material and radiation activities are widely used. This paper shows the lesson learned and challenge concerned radiation exposures in industrial fields. The minimum requirements for licensee during operation gamma irradiation facility were radiological monitoring system, safety or interlock system, operation and emergency procedures, radiological protection, individual...
Abstract
Air quality is very important topic in radioisotope production facility. It is mandatory for some operators to be available behind hot cell to practice some activities concerning maintenance and operation. One of these tasks is redundant transferring Radioiodine from cell to QC lab and vice versa for measurements. Contam3.2 is a simulation model from NIST (National Institute of...
Over the last twenty-five years, the Centre of Isotopes (CENTIS) of the Republic of Cuba manufactured of a wide range of radioactive products for healthcare, life science research and industrial applications and realized biodistribution and pharmacokinetic studies. These practices generally have not a significant occupational exposure but it is necessary to adopt dose constrains from ALARA...
ABSTRACT:
Occupational radiation dose of staff handling over 200 radioactive sources at the radioactive waste and workplace assessment in Radioactive Waste Management Centre (RWMC) of Ghana Atomic Energy Commission (GAEC) have been undertaken to determine levels of radiation safety. Firstly, five permanent workers were provided with thermoluminescent dosimeters (TLDs) to wear in between the...
The aim of this study is to assess the occupational exposure during radiological emergency in the Center of Isotopes of the Cuban Republic, taking into account the data belonging to the period 1997-2021. A total of 240 abnormal occurrences are registered and 80% of them were classified as an alert situation. The permanency of worker in a local with Technetium generator drove the maximum value...
The paper describes in detail the analysis of all risks that may occur during the operation of the Radiation Facility. All risks in the Radiation Facility can be divided into three categories:
1. Risks in routine use
2. Risks in special operations
3. Accidents
- Risks in routine use can be:
a) Risk of irradiation of employees in the irradiation cell
There are three openings where a...
Abstract
The research reactor TRR is in operation more than 50 years; at the same time the reactor technical condition allows its further safe operation in the case of upgrading of some systems and elements. The basic objective of the reactor modernization implies future utilization complying with the nuclear and radiation safety requirements. The radiation protection system is the subject of...
Synchrotron radiation source (SRS) is a unique photon source of high brightness with a broad energy range extending from infra-red to hard x-ray. SRS is essentially a storage ring in which relativistic electron beam is stored in the vacuum chamber for several hours during which synchrotron radiation is emitted tangential to the circular path of electrons. The radiation is then transported to...
