The use of γ-rays for industrial flaw detection is one of the important means of non-destructive testing technology. However, due to the inherent safety of the traditional gamma radiography that cannot accurately identify the location of the radioactive source, the interlock system between the shielded exposure device and the guide tube has some inherent flaws in use, etc. Gamma radiography...
Taking the Code of Conduct on Technological and Physical Safety of Radioactive Sources, States have the obligation to protect people, society and the environment from sources that are in disuse, which is why they must create various systems for the control of these sources. However, there are nations that have abandoned sources in spaces where civilians can enter without permission and with...
The National Center for Energy, Science and Nuclear Techniques (CNESTEN) has Implemented safety and security measures. For the use and import of radioactive sources, throughout their life cycle. These measures are applicable from their import to their final disposal, and they include:
-The importation of radioactive sources, after obtaining the import authorization issued by the Moroccan...
To follow the radiation safety rules depending on generated actual radiation power i.e. exposition dose rate (EDR) in different locations of source work places is an assessment of its side effects on the environment, especially on human health.

The Cobalt‑60 (Co-60) teletherapy machine was invented by University of Saskatchewan medical physicist; Harald E. Johns in 1951 in Saskatoon, Canada and has been used widely for cancer treatment. Commonly applied for external beam radiotherapy procedure, this machine uses Co-60 with high specific activity that emits high-energy gamma rays to kill cancer cells. Based on the IAEA Code of Conduct...
For radiation protection purposes, the narrow-beam series (N-series) radiation qualities are of great importance, for the definition of the reference fields which are standardized for all secondary calibration laboratories by the ISO 4037 standard, indeed this beams qualities are defined by their photon energy distributions. Determining this energy distribution usually requires complicated...
The supplementary guidance under the Code of Conduct, Guidance on the Management of Disused Radioactive Sources, advises that regulatory provisions should be established for acquisition and use of a radioactive source, that include adequate financial provisions to cover the costs of management once the radioactive source becomes disused. The financial resources for the management of disused...
The possibility that radioactive sources could be used for malicious purposes cannot be ruled out in the current global situation. Today, there is a growing concern that terrorist or criminal groups could gain access to high activity radioactive sources and use the sources maliciously. Then, security of radioactive sources has long been a matter of national and international concern. States...
The Radiation unit, a gamma sterilization facility at the Vinca Institute of Nuclear Sciences, is one of over 200 gamma irradiators operating worldwide. Gamma radiation is used for a variety of products: syringes, surgical gloves, gowns, masks, adhesive patches, dressings, ‘tetrapacks’, pacifiers for premature babies, artificial joints, food packaging, raw materials for pharmaceuticals and...
Samples of borosilicate glass-matrix were obtained by preliminary melting of a mixture of a calcined solution-simulator of LRW of NPP with WWER-1000 reactors with addition of glass-forming silicon oxide, in the form of sand, and 10 wt. % lead oxide or calcium fluoride, followed by glass-melting and pouring glass into metal molds.
Simulated γ-irradiation of borosilicate glass-matrix samples...
1 Introduction
The Ghana Revenue Authority, Customs division is recognized as one of the key Front Line Officers who play a significant role in detecting radioactive materials at border entry points. These officers use handheld nuclear security detection equipment as a secondary detection strategy, though X-ray scanners are the primary equipment used to inspect cargo shipments at the country's...
Définition :

The approving of UNSCR-1540 (2004) and new international tools in nuclear security area, shows that the world community has embarked on a long-term campaign to prevent non-state actors from acquiring and using weapon of mass destruction and related materials. The protection against the theft or sabotage of nuclear/radioactive materials and facilities is a major focus for Republic of Moldova,...
Risks are generally approached intuitively with the sole objective of minimizing its consequences. However, the mechanisms for achieving it are often unknown. Although the actions to reach this main goal are apparently simple, in this study some relevant complexities are analyzed. As an initial premise, it must be remembered that all human activities, including life itself, carry some type and...
Abstract
Implementation Guides provided guidance on the means by which states can implement and take the actions set forth in the Nuclear Security Recommendations. In this way, we will be able to know the reflection and compare the procedures required in the implementation manual for the safety of transporting, storing and using radioactive materials under category (A) and the...
Korea revised the regulatory requirements for high-risk radioisotopes in 2015 to reflect IAEA security standards.
Sealed radioactive isotopes above the level of regulatory exemption under the BSS are subject to graded regulations under the Nuclear Safety Act, and additional security requirements such as designation, access control, detection, confirmation, and response are applied to IAEA...
Abstract
It is of a great concern to countries regarding Illicit trafficking of radioactive sources across country’s borders; this has become a problem from radiological hazard point of view. The regulations and procedures set to ensure the control of radioactive sources is to prevent and detect illicit trafficking of radioactive sources. Preventive and detective measures should be taken...
Nowadays radioactive sources are one of the most used technique to destroy tumor cells in patient by megavoltage or kilovoltage photon beam. Klaipeda university hospital in Lithuania uses sealed 60Co source of ionizing radiation and a linear accelerator (linacs) in its activities. In this field radiation protection and physical security plays a very important role in safety of ionizing...
The Law on Radiation and Nuclear Safety and Security of the Republic of Serbia [1] regulate activities of radiation and nuclear safety and security, conditions for performing activities with radiation sources, acting in the situation of planned, existing, and emergency exposure to ionizing radiation to protect individuals, population and environment from the harmful effects of ionizing...
Radioactive sources are being extensively used in medicine, agriculture, industry, research & education and other sectors in Bangladesh. The usage of radioactive sources is rising day by day with the socio-economic development of the country. The Bangladesh Atomic Energy Regulatory Act-2012 (Chapter IV, vide 29-31) & Nuclear Safety and Radiation Control Rules-1997 of Bangladesh (vide 17-19)...
An effective self-assessment is a great tool to measure the strengths and flaws of security culture in an organization. A strong security culture in the organization can identify the obstacles and incentives for enhancement of security performance. This is considered as one of the main approaches in reducing the threats, especially coming from the insider. Recognized as the pioneer country to...
