Assessment of radiation absorbed dose in radiation contaminated area are of greater value in radiation protection field. In this project three radioactive source involved Na22 , Ba133 and Cd109 whose main emission are gamma ray. Calculation were done to compute the radiation absorbed dose by skin and soft-tissues using mathematical equation .The main parameters of this project are the distance from the radioactive source , activity and type of radiation sources. The results showed that the amount radiation absorbed dose at time considered didn’t produce significant effect since it not reach 2 Gy where the highest values of skin dose was (0.001137187, 0.000285321and 0.000175802 mGy) for Na22, Ba133 and Cd109 respectively and for soft-tissues was(0.001144353,0.00028630 and 0.000187827 mGy ) for Na22,Ba133 and Cd109 respectively
