Radon studies in the living environment in central and eastern Europe countries

There is a currently growing interest in the effect of exposure to 222Rn, because it became recognised as an important “pollutant” factor of the environment. Possible lung cancer incidence due to exposure to environmental radon levels may thus account for

Nitrous oxide pollution: a geostatistical method to assess spatial distribution of anaesthetic gases and hospital staff exposure.

In this study we evaluated the diffusion of nitrous oxide in a few operating rooms, using spatial data modelling techniques, in order to assess hospital staff exposure and to promote risk management. Indoor air sampling was carried out, during routine operating activity, by means of transportable infrared spectrometer, with geostatistical techniques. We detected high average concentrations of nitrous oxide (from 8 ppm to 445 ppm, with a peak of 1345 ppm).
