Two 7Be-related properties have been measured using a high-efficiency germanium gamma spectrometer (relative efficiency of 90%), namely, the activity median aerodynamic diameter (AMAD) of 7Be-associated atmospheric aerosols and the airborne 7Be radioactivity. With time resolutions of about 1-3d correlations between these 7Be-related properties and different meteorological parameters were identi...

Objective: To assess the results of monitoring radiation indicators state environment in Zaporizhzhia region under threat a accident at NPP order to make decisions regarding use countermeasures. Materials and methods: As result analysis long-term observations, radioactivity event were determined. More than 21,000 measurements gamma background territory carried out 13 settlements region. The dos...

The radioactivity in human tissues (lungs) obtained from the dead body of people who died by lung cancer in the region of Ptolemais, Northern Greece, where 16 units of 4 major coal-fired power plants are in operation, was studied. The specific activities of radioactive nuclides searched for in human tissues were not remarkable. The syndrome of lung cancer deaths at that area which showed an inc...

On Saturday, April 26th, 1986 at 1:23 am, Block 4 of the nuclear power plant at Chernobyl exploded. The plant was located approximately 100 km north of the Ukrainian capital Kiev, near the border with Belarus. 180,000 kilograms of highly radioactive material is inside the reactor at the time an amount equal to 1,000 Hiroshima bombs. About 1019 Bq of radioactive material – consisting of at least...

Radioactivity measurements for water, soil, and air have been completed in national international regions. The radioactivity process is randomized occurs naturally by primordial nuclides. Another case hand-made reactions which realized artificial reactions. high rate of the total dose radiation, whichever exposed to humans, originates as Natural Radioactivity. In this case, environmental are im...

There is no evidence that natural radiation (cosmic radiation or from natural radioiosotopes) increases the risk for thyroid diseases. Moreover, while it has been proven that exposure to external medical radiation or to external and internal radiation by atomic bomb explosions leads to an increased risk for thyroid cancer, the medical use of radioiodine, namely diagnostic and therapeutic applic...

As the nation's industrial complex grows, one of its attendant evils—environmental pollution—grows apace. Perhaps no segment of this complex grows more rapidly at present than the atomic energy industry. Responsible officials are gradually becoming aware of the potential for pollution of this new giant. The problem is complicated by security requirements and by virtue of the inability to sense ...
