[Assurance of safety and personal protection of the personnel working in conditions of external radiation exposure].

The article contains detailed analysis of current scientific approaches and practical achievements in organizing personal protection of the personnel working in conditions of external radiation exposure and air and surface contamination with radioactive substances. The ways of improvement of personal protection equipment are described. The incorrectness of attempts to create PPE from gamma radiation with the energy of over 0,1 MeV--which are currently quite common--is shown.

[Ways of increasing the operational and protective properties of anti-mercury respirators].

The major results of studies on the assessment of the dynamic activity of sorption--filtering respirators relative to mercury vapours are presented. It has been shown that the term for the storage of the respirator "Lepestok-G" can be increased from 6 months, starting from the date of production--according to the established technical rules, --up to 2 years. The surface density of the sorbent can be reduced from 3.
