Measurement of radon activity, exhalation rate and radiation doses in soil samples from Banda district, India

Radon activities and radon exhalation rates have been measured in soil samples collected from different location of Banda district of Uttar Pradesh in India using LR-115 type II solid state nuclear track detectors. Radon activity has been found to vary from (101.0) to (505.1) Bqm⁻³ with an average value of (278.3) Bqm⁻³. Mass exhalation rate has been found to vary from (2.1) mBqkg⁻¹h⁻¹ to (10.6) mBqkg⁻¹h⁻¹ with an average value of (5.8) mBqkg⁻¹h⁻¹. Indoor inhalation exposure (radon) effective dose has been estimated which is found to vary from (6.1) to (30.5) μSvy⁻¹ with an average value of (16.8) μSvy⁻¹.
