الملخص EN

Among radiation exposure pathways to human beings, inhalation dose is the most prominent one.

Radon, thoron, and their progeny contribute more than 50 per cent to the annual effective dose due to natural radioactivity.

South west coast of India is classified as a High Natural Background Radioactivity Area and large scale data on natural radioactivity and dosimetry are available from these coastal regions including the Neendakara-Chavara belt in the south of Kerala.

However, similar studies and reports from the northern part of Kerala are scarce.

The present study involves the data collection and analysis of radon, thoron, and progeny concentration in the Wayanad district of Kerala.

The radon concentration was found to be within a range of 12–378 Bq/m3.

The thoron concentration varied from 15 to 621 Bq/m3.

Progeny concentration of radon and thoron and the diurnal variation of radon were also studied.

In order to assess source term, wall and floor exhalation studies have been done for the houses showing elevated concentration of radon and thoron.

The average values of radon, thoron, and their progeny are found to be above the Indian average as well as the average values reported from the High Natural Background Radioactivity Areas of Kerala.

Exhalation studies of the soil samples collected from the vicinity of the houses show that radon mass exhalation rate varied from below detectable limit (BDL) to a maximum of 80 mBq/kg/h.

The thoron surface exhalation rate ranged from BDL to 17470 Bq/m2/h.
