ABSTRACT: Rn-222 is the most
important source of natural radiation and is responsible for approximately half
of the received dose from all sources. Most of this dose is from inhalation of
the Rn-222 progeny, especially in closed ares. Portable alpha particle
detector, RAD7 was used for Rn-222 measurements inside the main campus of
Aljouf University at Saudi Arabia in order to estimate the effective dose to
the occupants from 222Rn and its progeny. The values of annual effective
doses for radon inhalation by the inhabitants were found to vary in the range
0.08 - 0.80 mSv/y, with a mean of 0.4 mSv/y. These results are lower than the
value 1 mSv/y recommended by ICRP, 1990. The variation of dose relationship
from indoor radon in lung tissue is calculated and tabulated. In addition to
environmental value of the present survey, the results are considered to be
essential in analyzing any data for future activities in this field.
