Research on change of natural ionizing radiation in car parking places
Santrauka
The change of natural ionizing radiation in underground, aboveground and com- 10 pound parking places has been researched in the article. The equivalent dose rate of 11 natural radionuclides in building materials has been measured and its change has been 12 evaluated. The specific activities of natural radionuclides contained in building struc- 13 tures have been spectrometrically measured. The activity index and radium equivalent 14 activity allowing to evaluate appropriateness of each material for such buildings from 15 the point of radiation safety, have been determined.
