This is an overview of the strategy used to describe the effects of a potential release from a radioactive waste repository on human exposure and future environments. It introduces a special issue of AMBIO, in which 13 articles show ways of understanding and characterizing the future. The study relies mainly on research performed in the context of a recent safety report concerning a repository ...

Cyanate inhibits sickling and prolongs red cell cell was not impaired, and free intracellular survival in sickle cell anemia. However, cyanate amino acid was not carbamylated. Aminoacylamarkedly inhibits hemoglobin synthesis in vitro. tion of transfer RNA was not inhibited; the Incorporation of radioactive amino acid into acylated amino acid was not carbamylated. hemoglobin by human sickle reti...

In order to obtain an insight into the mechanism of experimentally induced redifferentiation of cancer cells, changes in negative charge of the cell membrane were examined by cytopherometry following in vitro exposure of the cancer cells to non-radioactive gallium. Reduction of the negative charge was observed at 24 hr and later. The gallium ions must have neutralized the negative charge of the...

Kori Unit 1, which was permanently shut down in 2017, is expected to be the first decommissioned commercial nuclear power plant (NPP) Korea. Operating NPPs designate radiation-controlled areas (RCAs) protect workers from radiological hazards and provide appropriate measures. Decommissioning RCAs (DRCAs) being should also designated by considering characteristics of workplaces exposure routes de...

Workers at U.S. facilities that use radioactive materials are subjected to a small occupational health risk. The Nuclear Regulatory Commission sets standards to ensure their safety. The agency limits worker doses to no more than five rem (5,000 millirems) per year and requires that occupational doses be kept “as low as reasonably achievable.” Radiation workers are individually monitored to reco...

the present study investigates the effect of different exposure densities on third grade iranian junior high school (ijhs) students’ efl development and retention. it also attempts to explore whether there is any differential performance due to type of post-exposure assessment tasks (recognition vs. written production). performances of five groups of learners receiving equal amount of exposure ...

radiations might affect nucleic acid metabolism was that by Mitchell (10), who observed that,cells of hunian malignant tumors showed an increase in. the absorption of ultraviolet light after exposure to xand 7-rays. Evidence that irradiation inter feres with the synthesis of deoxyribonucleic acid (DNA)' has been demonstrated repeatedly by methods with radioactive tracers. A review of the litera...

The article by Wing et al. (1) introduced the idea of calculating the relative intensity of radioactive fallout between sectors of a circle drawn around the accident at Three Mile Island. The partition derived from wind and weather data allowed a comparison of ratios of radiation exposure between sectors with cancer incidence ratios and bypassed much of the uncertainty involved in calculating a...

Radiotherapy is cancer therapy using radiation. One of the tools used for radiotherapy Linac. Using Linac also can have a detrimental effect on radiation workers, patients, and public. The reaction cause activation around room to become radioactive. Therefore, protection needed. This research aimed measure environmental exposure as effort bunker. uses quantitative method by collecting data dire...
