Concentration factors used in the assessment of radiation dose to consumers of fish: a review of 27 radionuclides.

abstract：:Small plastic chambers containing alpha track detectors are often used for measuring indoor concentrations of 222Rn. This paper reports an experimental assessment of sources of error in measurements made with alpha track detector-containing chambers. The results demonstrate the feasibility of a nondestructive test for...
