Swipe assays are routinely performed in laboratories and other facilities that use or handle radioactive materials. These assays, often referred to as smear or wipe tests, are performed to comply with radioactive material license requirements, assure laboratory safety, and provide information that proper handling procedures are being followed. Typically, swipes are performed to monitor for the ...

This paper uses discrete choice models, supported by GIS data, to analyse the National LandUseDatabase, a register ofmore than 21,000 English brownfields—previously used sites with orwithout contamination that are currently unused or underused. Using spatial discrete choice models, including the first application of a spatial probit latent class model with class-specific neighbourhood effects, ...

Low-level radioactive contamination may affect choice of breeding site and life-history decisions if (i) radioactivity directly affects body condition or (ii) it affects resource abundance that then secondarily influences reproductive decisions. We tested the effects of radioactive contamination on nest-site choice and reproduction in a community of hole nesting birds by putting up nest boxes i...

All of these materials are transported on land, sea or in the air in compliance with regulations which are now universally based on the IAEA Regulations for the Safe Transport of Radioactive Materials Ref. [1]. These regulations are designed to ensure adequate protection of transport workers, the public and the environment against the hazards of external radiation, the spread of radioactive con...

Sperm are highly susceptible to reactive oxygen species (ROS) that can damage sperm DNA and structure, resulting in reduced fertilizing capacity. Exposure to radioactive contamination can also impair sperm swimming behavior and fertilizing ability, both through a reduction of sperm DNA integrity and via an increased generation of reactive oxygen species (ROS). However, the relationship between ...

This work compares the radioactive consequences due to the Chernobyl and Fukushima NPP accidents. Due to non-homogeneous features of the fallouts of radioactive isotopes in the both cases the comparison of radioactive contamination density was compared for similar administrative units – in Russia (Bryansk region, Novozibkov subregion) and in Japan (Fukushima prefecture, Namie municipality). We ...

conclusions: this study provides detailed information and case samples of radiodine contamination artifacts and non-physiological, non-metastatic extra-thyroidal i-131 accumulation in whole-body i-131 imaging. introduction: radioactive iodine has been used for more than 50 years for the treatment of thyroid diseases. differentiated thyroid cancers have the ability to trap iodine. therefore, rad...
