Abstract

Instruments for the measurements of radon, thoron and its decay
products in air are based mostly on the detection of alpha particles.
The health hazards of radon on general public are well known. In
order to understand the level and distribution of 222Rn concentrations
indoor in Al-Fallujah City; new technique was used, this technique
was three radon–thoron mixed field dosimeters is made up of a twin
chamber cylindrical system and three LR-115 type II detectors were
employed. The aim of this work was to measurement radon gas using
SSNTD technique door in in Al-Fallujah City, and estimation of
excess in cancer due to increment in radon gas. Results for samples
which are collected from January to April 2013 show that the 222Rn
concentration varies from 52.33 to 108.70 Bq.m-3 with an average of
84.64 Bq.m-3, according to EPA and ICRP, the average indoor radon
level should be 148 Bq/m3 and 300 Bq/m3, respectively, whereas
approximately 15 Bq/m3 (ranging from 1 Bq/m3 to 100 Bq/m3 of
radon concentration is normally found in outside air. Also the values
of annual effective dose and excess lung cancer per million people
per year (ELC) have also been calculated and found to vary from
0.941 to 2.350 mSv.y-1 with an overall average of 1.581 mSv.y-1 and,
565 to 1410 with an overall average 948, respectively.
