The indoor radiation mainly comes from
radon. After inhalation its daughters stay in the lungs and become a permanent
source of radiation and may cause lungs cancer. The indoor radon originates
from soil and building materials with soil as the main source. Water is also a
source of radon and it contributes to the indoor activity through taps and

in the less ventilated places. In the present work, the exhalation rate of
radon from soil has been estimated.
A number of soil samples were collected from the city of
