Abstract
The work presented here summarises the results of four tests, in which a RaS (a Tc-99 m olution) was dispersed over a free area with the use of an industrial explosive. Detection methods and techniques employed in these tests are escribed and values characterising the RaS dispersion—dose rates, surface activities in horizontal and vertical directions, volume activities, their space and time distributions and mass concentrations of aerosols produced after the explosion are presented and compared.
These data will be applied to a comparison of outcomes of models used for the assessment of radiation accidents as well as in future field tests carried out under conditions of more complex geometry
