[A radiation hygiene assessment of the use of the deicing preparation Kama-M in Moscow].
The content of radionuclides and metals in the agent to control the ice-crusted ground Kama-M was determined. An investigation has shown that the radioactive background of the agent is caused only by the presence of 40K as part of KCl. Small quantities of 226Ra and 232Th are present in the insoluble sediment. The concentrations of metals are very low and produce no environmental effects. The levels of superficial pollutions vary from 1.3 to 4.8 beta-particles per cm2/min and the power of an exposure dose is at the level of background values (9-20 microR/hour), which is no greater than the permissible ones.
