| Abstract |
Airborne radioactivity in mines can reach hazardous levels even where no obviously radioactive mineral is present. Field trials involving measurement of alpha activity of shift-long respirable dust samples were carried out over 8 months using the MRE gravimetric dust sampler: the value obtained was fairly close to a shift average. The theoretical basis of the method is described in great detail. Since there was no significant difference between the radioactivity levels calculated from respirable and total dust samples, it was possible to use standard respirable dust samples for routine work. |
