On-line educational means were developed, which assist training in Radiation Protection and in Accelerator Technology Safety, in Radiotherapy Departments and Industrial Sterilization Facilities. Hypertext and multimedia courseware are gaining importance in University and Professional Education, and may partially release the teaching staff, and offer them more time to concentrate on more substan...

The paper addresses the international policies and strategies for the remediation of land contaminated by radioactive material residue, its main aim being to describe the misunderstandings, evolution and status of the international paradigms in this area. Thus, the denotation and connotation of the 'remediation' and 'contamination' concepts are explored, including the ambiguity they produce in ...

OBJECTIVES To evaluate radiation protection basic knowledge and dose assessment for radiological procedures among Italian radiographers METHODS A validated questionnaire was distributed to 780 participants with balanced demographic characteristics and geographic distribution. RESULTS Only 12.1 % of participants attended radiation protection courses on a regular basis. Despite 90 % of radiog...

Recent research in molecular radiation carcinogenesis is reviewed with the specific aim of exploring the implications this research may have on the dose response relationship of radiation-induced cancer at low doses and low dose rates. It is concluded that the linear non-threshold dose response hypothesis may be used in radiation protection planning as a simple, convenient method to optimize pr...

Previous studies have shown that physicians tend to underestimate the risks to patients of radiation exposure. This study in 2 Palestinian hospitals aimed to assess physicians' knowledge about the risks associated with the use of radiological examinations. A questionnaire answered by 163 physicians revealed many gaps in knowledge. Only one-third of physicians had received a radiation protection...

This instructional material is intended to provide the user with the best available information concerning what is currently known about the health risks from exposure to ionizing radiation. A question and answer format has been used. The questions were developed by the NRC staff in consultation with workers, union representatives, and licensee representatives experienced in radiation protectio...

Textiles can provide effective protection against UV radiation because they reflect, absorb and scatter solar wavelengths. Properly designed, they significantly increase the area of covered skin. The optimal combination of thickness, fabric density, mass per unit area, knitted structure, yarn type and yarn linear density, facilitate the production of textiles with high UV protection properties....

human activities such as oil and gas production can enhance the natural level of naturally occurring radioactive materials (norm) in by-product and waste streams. iran has been among the top five oil producing countries since 2005. this high production rate emphasizes the importance of norm management to ensure the safety of humans and wildlife. petroleum storage and transport facilities are lo...
