The objects of development and investigation are as follows: a) state primary measurement standard for the unit of volumetric activity of alpha-emitting aerosols in the range of 10 to 10*10 Bq/m*3; b) state primary measurement standard for the unit of volumetric activity of beta-emitting aerosols in the range of 10 to 10*10 Bq/m*3; c) state primary measurement standard for the unit of volumetric activity of gamma-emitting aerosols in the range of 10 to 10*6 Bq/m*3. The objective of the work is to assure the uniformity, reliability and required accuracy of volumetric activity measurements for alpha-, beta-, gamma-emitting aerosols. The development method is to use the experience of the world science in the field of ionizing radiation of nuclear constants their measurement and metrological assurance in terms of generators of alpha-, beta-, gamma-emitting aerosols; Plutonium-239, Strontium-90 + Yttrium-90, Iodine-131, Uranium-238, Thallium-204, Cesium-137standard sources; ЕP12-08-АB, ЕP 12-10-G transfer standards. The research method is to make theoretical and experimental evaluation of the measurement ranges and errors for volumetric activity of alpha-, beta-, gamma-emitting aerosols.
