[Radiation hazard in the use of radioisotopic neutralizers of static electricity].

Spectrometry was used by means of an alpha-radiometer on a [symbol: see text]porpecc-[symbol: see text] hard-and-software complex to study the radioactive contamination of the surfaces of neutralizers with plutonium 239-based ionizing radiation sources, which are employed to remove electrical charges from electrifiable materials. While using the neutralizers, the operating personnel is shown to be exposed to radiation. The level of removed radioactive contamination during half-a-year exploitation of the neutralizers was greater than the maximum allowable values on the average by several times.

[Occupational estimation of the levels of mercury in workers engaged in electrochemical manufacture of caustic soda].

Plasmaless atomic absorption was used to study biosubstrates from the workers engaged in the production of caustic soda for the levels of mercury. In 63% of the examinees, the urinary concentrations of mercury exceeded the critical value and substantially increased after administration of a detoxifying agent. The content of mercury in the hair was also higher than the physiologically allowable normal value.
