Rn-222 is the mostimportant source of natural radiation and is responsible for approximately halfof the received dose from all sources. Most of this dose is from inhalation ofthe Rn-222 progeny, especially in closed ares. Portable alpha particledetector, RAD7 was used for Rn-222 measurements inside the main campus ofAljouf University at Saudi Arabia in order to estimate the effective dose tothe occupants from 222Rn and its progeny. The values of annual effectivedoses for radon inhalation by the inhabitants were found to vary in the range0.08 - 0.80 mSv-y, with a mean of 0.4 mSv-y. These results are lower than thevalue 1 mSv-y recommended by ICRP, 1990. The variation of dose relationshipfrom indoor radon in lung tissue is calculated and tabulated. In addition toenvironmental value of the present survey, the results are considered to beessential in analyzing any data for future activities in this field.
