Background: Since 1996 the assessment of
environmental gamma radiation dose in residential
areas of Iranian towns and cities has been
accomplished for 10 counties. As a practical method
and based on the results of a pilot study, in order to
attribute the final results to the whole residential area
of a town five stations were selected for every town.
The location of individual station was studied closely
to comply with recommended conditions in the
literature. Materials and Methods: RDS-110 was
employed to measure gamma dose rate for one hour.
Average annual dose rates plus conversion
coefficients were employed to estimate gonad, bone
marrow, equivalent and effective dose. Result:
Minimum and maximum annual bone marrow and
gonad dose equivalent attributed to environmental
gamma are 0.24 mSvy-1 (for both tissues) and 1.44
and 1.46 mSvy-1, respectively. Conclusion: Average
gonad and bone marrow doses for North Khorasan,
Boshehr and Hormozgan provinces were less than
the corresponding values for normal area. Iran. J.
