- Abstract
- In the course of carrying out the integrated experiments parameters of the main technological operations of hydrochloric acid technology of the perovskite containing natural radionuclides are optimized. The radiation assessment of technology and final products is carried out. It is shown that the main technological product is cleared of radionuclides: effective specific activity of dioxide of the titan is equal 94 Bq/kg. The representative sample of technical dioxide of the titan which physical and chemical characteristics meet the requirements of GOST 9808-84 is received. According to radiation safety standards NRB-99/2009 the address agrees with such technological product and its use for various purposes can be carried out without restrictions on a radiation factor.
