Indoor radon/thoron have been recognised as one of the health hazards for mankind.
Common building materials used for construction of houses, which are considered as major sources of these gases in indoor environment, have been studied for exhalation rate of radon/thoron.'Can'technique using plastic track detector LR-115 type-II has been used for measurement.
Exhalation rates for radon and thoron have been found to be varying from a minimum value of 0.024 and 29.4 Bq m-2 h-1 for cement plastered brick to a maximum value of 0.16 and 692.2 Bq m-2 h-1 for unfired brick, respectively.
Exhalation rate for thoron has been found to be several times higher than that for radon.
Measured exhalation rates for thoron indicate significant presence of thoron in indoor environment which is also supported by indoor measurements of thoron and its progeny.
