Radon exhalation rate and mean annual effective dose from radium concentration from Gharraf canal and its some branches in Thi Qar governorate (Iraq)‎

Abstract EN

The radon exhalation rate in term of area was variable (10.4-52.1 mBq.m-2.h-1) with the average value (30.1 mBq.m-2.h-1) while the radon exhalation rate in term of mass was variable (1.09-5.45 mBq.kg-1.h-1) with the average value (3.15 mBq.kg-1.h-1) and radium concentration is varied (0.144-0.722 Bq.kg-1) with the average value (0.417 Bq.kg-1).

The annual effective dose of radium for three population groups was carried out, and lifetime risk assessment was about 10-4 when used this water as a drinking water.

The results compared with safe recommended limit to radium concentration and the annual effective dose of radium in drinking water according to WHO and with other countries.
