	%X The measurements of 226Ra, 232Th and 40K using
gamma spectrometry and radon concentration and exhalation rates
measurements using solid state nuclear track (LR-115, Type-II
plastic) detectors are used to asses a first order exposure risk for the
persons residing in Fatehbad and Hissar districts of Western Haryana,
India. The concentration of Radium, Thorium and Potassium in the
soil samples varies from 13.37 Bq m-3 to 24.67 Bq m-3, 34.67 Bq m-3
to 67.34 Bq m-3 and 298.78 Bq m-3 to 405.67 Bq m-3 respectively
with average values of 18.78, 47.35 and 361.57 Bq m-3 respectively.
The radium equivalent activity (Raeq) calculated for the same soil
samples varies from 92.72 Bq m-3 to 140.6 Bq m-3 with an average
value of 111.80 Bq m-3. The values of absorbed dose and annual
effective dose (indoors and outdoors) are found to vary from 44.18
nGy h-1 to 65.23 nGy h-1, 0.22 mSv y-1 to 0.32 mSv y-1 and 0.05 mSv
y-1 to 0.08 mSv y-1 respectively. The radon concentration and
exhalation rates have also been reported. The radium equivalent
activities in all the soil samples were found to be lower than the limit
(370 Bq kg-1) set in the Organization for Economic Cooperation and
Development (OECD) report and the value of Hex in all the samples
is less than unity.
