Abstract

Natural sources imply cosmic radiation, terrestrial radiation and natural radionuclides in water and air. Natural sources of radiation may be also concentrated in the environment by human activities. Examples of these are uranium mining, transport and deposition of U-ores and barren rock, uranium processing, coal mining, and the use of phospate and potassium fertilizers in agriculture. The use of man-made radioisotopes in industry, nuclear power plants and various man activities may result in their escape, transfer and deposition as nuclear fallout. Geophysical radiometric methods have the capacity of location, monitoring and assayss of these various bulk radiation sources in the environment and enable estimates of their radioactivity levels and their assessment.
