Abstract: A sealed radioactive source, typically called a sealed source, refers to radioactive material that has been sealed inside a capsule or is permanently bonded in a solid form. Sealed Sources within devices are commonly used to deliver a defined Dose of radiation, such as that used in cancer therapy or in irradiators that sterilize food and medical equipment. In Tanzania the use of...
In Ghana, radioactive sources are used daily and widely in medicine for both diagnosis and treatment such as radiotherapy, in the mining, oil and gas and in agriculture for human prosperity and wellbeing. Radioactive sources are also applied in research and education, industry and the military and are found throughout the world. Due to the widespread use of these sources, there is emphasis to...
Gamma spectrometry is an efficient method of identifying and quantifying radioactivity. The ionizing radiation emitted by radionuclides is invisible and untouchable. Detectors are then used to “observe” them. When a gamma photon interacts inside the semiconductor of a detector, charge carriers are created and then carried to electrodes by an applied potential difference. The charge transport...
Selective internal radiation therapy using Yttrium-90 labelled microsphere is increasingly used to treat hepatocellular carcinoma. Based on its properties, Yttrium-90 can produce bremsstrahlung radiation which is essential for post treatment localisation and dosimetry. However, bremsstrahlung radiation could lead to increase of radiation exposure to radiation workers. The aim of this work was...
ABSTRACT
The application of ionizing radiation is an important technique for a wide variety of industries in many cases. One of these applications is portable density/moisture gauges. Portable density gauge has been used in industries such as construction, civil engineering, agriculture, and the like areas to perform in-situ measurements such as soil moisture or asphalt density....
In Chile, the physical protection of nuclear facilities and materials has been regulated since 1985 [1]. However, the physical security of radioactive materials was established as a requirement, with the publication of the regulation for the physical protection of radioactive materials, in July 2020 [2].
The new regulation establishes requirements for the protection of radioactive materials...
In Mauritania thousands (Is it realistic??) of packages with radioactive materials have been arriving and starting all the year.
There are three main entrance points: The ports of…., the borders with morocco, Mali……, the airport.
Every point of entrance has monitoring protocols and procedures and there is a need to verify their interface to ensure both safety and security.
Ship...
Disused sealed radioactive sources are used in many fields such as industry, medicine, civil engineering, agriculture, research and educational applications. However they must be controlled from manufacturing to disposition, which requires a big deal of awareness, commitment and mobilization of all the necessary resources in order to be managed safely and securely in line with the IAEA...
Abstract
The present study investigates commercially available ion paint, evaluation being made using gamma-ray spectroscopy and Geant4 Monte Carlo simulations. A particular concern being the daily inhalation exposure dose. Organ doses have been simulated using the MIRD5 mathematical phantom, with incorporation of dose conversion factors. Sample code IP04 was found to contain the greatest...
The prescriptions of radiation protection standards ensure the protection of users and medical personnel. They are applicable in all IAEA member countries, developed as well as non-developed. But the conditions of compliance are easier in developed countries than in developing countries because of the difficulties in the latter, linked to insufficient resources causing organizational...
Madagascar has an external radiotherapy center which uses a source of cobalt-60. Since this source of cobalt is Category One, extremely hazardous, joint safety and security measures have been implemented to ensure the safe and secure use of said source. The safety component covers the personal monitoring of workers under ionizing radiation, the zoning of work areas, the periodic monitoring of...
