the disposal of nuclear wastes is one of the most controversial issues faced by authorities in japan. in this regard, a survey was conducted among 172 university students to analyze the attitude towards the sitting of a nuclear waste repository in the country. the study focused on a number of variables that influenced the perception of risks before the 2011 tohoku earthquake and tsunami. result...
the treatment of thyroid cancer using an unsealed source of radioactive materials is usually associated with a large amount of 131i. a major problem for hospital admission of these patients is the waste disposal which requires protection of the public. 152 patients with thyroid cancer admitted to the nuclear medicine department of said ai- shohada hospital for ui i treatment were studied. 1311 ...
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...
Background Environmental regulations on medical waste incineration have become more stringent at the same time as landfill capacities are diminishing in many parts of the country. These two circumstances are leading many healthcare facilities to reevaluate their medical waste generation and disposal practices. Although the typical healthcare waste stream can include infectious, radioactive, and...
14C is one of the limiting radionuclides used in the categorization of radioactive graphite waste; this categorization is crucial in selecting the appropriate graphite treatment/disposal method. We propose a rapid analysis method for 14C specific activity determination in small graphite samples in the 1-100 μg range. The method applies an oxidation procedure to the sample, which extracts 14C fr...
