Natural radioactivity in Indian tea

Radiation and Environmental Biophysics, 1985
The paper presents the results of measurements on tea samples collected during 1962 and 1973-1983 period for their natural radioactivity content. The radioisotopes studied under this programme are radium-226, thorium-228, and potassium-40. Tea was found to contain higher concentration of these radionuclides compared to other foodstuffs having ...

Natural Radioactivity in Spanish Soils

Health Physics, 1994
The program of studies and surveys of natural radiation and radioactivity in Spain organized by our research group at the end of the 1980s included a 4-y national survey to determine the concentrations of natural radionuclides in soil. Results obtained from measurements of soil samples collected nationwide at > 900 sampling sites are reported and ...

Natural Radioactivity of Miami Soils

Science, 1960
An important part of man's radioactive environment is the natural radioactivity of soils. This radioactivity varies with soil type and with depth in the soil profile. The relation between gross gamma activity and soil depth for a particular soil (Miami silt loam) is presented, together with a discussion of the contribution of K

Natural radioactivity in Brazilian groundwater

Journal of Environmental Radioactivity, 2006
More than 220 groundwater samples were analyzed for 228Ra, 226Ra, 222Rn, 210Pb, U(nat), Th(nat), pH, conductivity, fluoride and some additional elements determined by ICP-MS. Since samples from several Brazilian states were taken, involving areas with quite different geologies, no general trend was observed relating the chemical composition and the ...

Natural Radioactivity

Physics Today, 1952
It may seem astonishing that after radioactive substances have been known for over half a century there should still remain important unsolved problems in the domain of natural radioactivity. This field was the first of the great subdivisions of nuclear physics to be explored, and yet much remains to be done here.

Natural radioactivity and radioactive waste disposal

Journal of Volcanology and Geothermal Research, 1992
Abstract The disposal of long-lived radioactive wastes by deep burial in suitable rock formations is an emotive issue. Although disposal is technically not exceptionally demanding, the demonstration of long-term safety using predictive hydrogeological and geochemical models has proved much more difficult.

Natural Radioactivity of Rhenium

Physical Review, 1962
The natural radioactivity of Re/sup 187/ was investigated by the method of internal gas-tube low-level Geiger counting. A half-life of (l.2 plus or minus 0.4) x l0/sup 11/ yr was found for the direct beta decay. Gas-tube proportional measurements suggest a value of about 3 kev for the maximum beta energy.
