CEMENT 222RN AND 226RA CONCENTRATION MEASUREMENTS IN SELECTED SAMPLES FROM DIFFERENT COMPANIES
Journal Title: ASIAN JOURNAL OF NATURAL & APPLIED SCIENCES - Year 2013, Vol 2, Issue 4
Abstract
Solid-state nuclear track detectors (CR-39) are widely used for radon exhalation rate measurements in cement under different conditions. The detectors were exposed to standard radon concentration from a standard 226Ra source. A calibration factor of 0.0107 track cm-2 per Bq d m-3 was determined. The 222Rn and 226Ra concentrations varied from 18Bq m-3 to 178 Bq m-3 and 0.09 Bq kg-1 to 1.30 Bq kg-1, respectively. The highest radon exhalation rate was found in Sulaymanyah, Iraq
