Study of radium and radon exhalation rate in some sand samples using solid state nuclear track detectors

الملخص EN

This study aims to assess the environmental hazards from radon exhalation rate in the sand samples in selected locations in Shaybah field in Saudi Arabia, using passive (CR-39NTDs) and active (SSBD) detecting method.

Radon concentration, effective radium content and radon exhalation rate were estimated in sand samples measurements.

The ranges of the obtained results are as follows: 10.96 to 12.62(Bq.m-1) for radon concentration active, 107.1 to 126.4(Bq.m-3) radon concentration passive, 22.4 to 19.5 Bqkg-1 for radium content, and the values of EA ranged from 6.19 to 31.1 (10-5Bq.m-2h-1) and values of EM range from 0.18 to 0.89 (10-5Bq.m-2h-1).

The results showed that there is a linear relationship between the ratio of radon concentration and the effective radium content in sand samples.

A comparison between our results with that mentioned in international reports was done.
