[Hygienic evaluation of contemporary light sources].

The article covers problems of illumination hygiene and electromagnetic safety of workers using contemporary light sources. The authors present results of experimental studies of electromagnetic environment in energy-efficient lamps.

Hematological and toxicogenomic effects of ferromagnetic screening of natural electromagnetic fields.

Aftereffects of ferromagnetic screening on the hematological and toxicogenomic parameters in rats were traced over 45 days. Two-day ferromagnetic screening of male and female rats (reducing permanent constituent of magnetic field induction by 4-10 μT) led to leukopenia observed on day 14 of the experiment. Life-time evaluation of the toxicogenomic effects was carried out by rapid method for measurement of blood nucleotide DNA by fluorescent indication.
