Characteristics of airborne radon- and thoron decay products

Objective



This additional proposal comprises three items:

1. The results of indoor radon measurements (with alpha scintillation cells and track etch detectors) in kindergartens and schools in Slovenia are intended to be used for dose estimation for children and personnel in this buildings.
For these purpose additional investigations would be necessary. Thus, within our participation in the EC project we plan to determine the radioactive equilibrium factor, the fraction of unattached radon daughters and the activity size distribution of radon daughters in several typical kindergartens and schools.
The selection of places to be investigated will be made according to radon levels, building material and structure, and meteorological conditions.
2. In connection to the research project "Introduction ot the Speleotherapy in Slovenia", simultaneous measurements of the radon and radon daughters concentration, the unattached fraction, the size distribution of aerosols and tne activity size distribution of the radon daughters in karst caves will be performed.
This research is important for the estimation of the etfective dose for the medical workers and for understanding the deposition of aerosols in the lungs and its influence on lung physiology.

3. Adsorbtion of radon and radon daughters on solid surfaces will be investigated.
A new highly-sensitive autoradiographic technique enabling the study of this effect has been already developed.
This technique in combination with other spectrometric and analytical methods will enable better understanding interactions of radon and its daughters with solid surfaces, and optimisation of atmospheric parameters and material properties for reduction of radon and radon daughters concentrations in air.
