ABSTRACT

Particular attention has been paid in recent years to the pollution of ambient air and production premises by radioactive and other substances owing to rapid development rates of atomic power generation, the electronic industry, use of aerosols in medicine, the pharmaceutical industry, etc. A number of organizational measures have been adopted in many countries to solve this problem; namely, work is in hand for developing and mass producing instruments for testing aerosols of all types and for raising the measurement precision. The most important problem consists of improving the existing metrologicalprovision means and, above all, those of highest precision.
