RADON DOSIMETRY USING CR_39 AS A TRACK DETECTOR

Solid state nuclear detector (CR-39) was used to obtain the concentration level of radon and its daughters, by using (Ra-266) of (10.54mCi) activity. It was employed for radon concentration and potential alpha energy exposure level. It is found increasing in track density with (absorbed dose, WLM, radon concentration in (PCi/liter), and potential alpha energy (PAEC)). The calibration curves were drawn by taking the linear part from the above curves. There is decreasing in absorbed dose with distance from the source. The linear response determine the detector range of (300-3X10^4 Bq/m^3 ), and the calibration factors was obtained for calibration (0.2 0.085 track/ mm^2 per Bq/m^3).
