【 摘 要 】

Background

The radiological quality of ²²⁶Ra, ²³²Th and ⁴⁰K in some samples of water resources collected in Anarak-Khour a desertic area, Iran has been measured by direct gamma ray spectroscopy using high purity germanium detector in this paper.

Result

The concentration ranged from ≤0.5 to 9701 mBq/L for ²²⁶Ra; ≤0.2 to 28215 mBq/L for ²³²Th and < MDA to 10332 mBq/L for ⁴⁰K. The radium equivalent activity was well below the defined limit of 370Bq/L. The calculated external hazard indices were found to be less than 1 which shows a low dose.

Conclusion

These results can be contributed to the database of this area because it may be used as disposal sites of nuclear waste in future.
