Measurement of Gamma Radiation dose for selected samples of Kufa University at Al-Najaf Governorate, Iraq

A background radiation dose at indoor and outdoor of medicine and engineering faculties laboratories were calculated in Kufa University at Al-Najaf governorate, Iraq. Measurements were obtained using a portable dosimeter survey “Inspector Alert model RAP RS1, S.E. international, Inc, USA”. Amount of minimum and maximum mean dose radiation were ranged from (19.622 to 69.904nGy/h) and from (8.277 to 16.249nGy/h) respectively. The Annual Effective Dose indoor and outdoor were calculated between (4.466 and 0.2S9mSv/y) successively. So, it's found lower than 1 μSv/y, Which is recommended by UNSCEAR (2000); therefore, these values are found to be safe.
