Equilibrium status among ²²⁶Ra and radon daughters was studied in soil samples around Rawatbhata, Rajasthan. It was found that the increase in radioactivity of ²¹⁴Bi (radon daughter) due to complete radon buildup in the sealed container is within 15% which establishes that ²²⁶Ra remains in equilibrium with radon daughter in soil of Rawatbhata. Radioactivity of ²³⁸U was estimated from the radioactivity of ²³⁵U using natural uranium isotopic radioactivity ratio (²³⁸U/²³⁵U) of 21.5. ²³⁸U radioactivity in soil was found in the range 25.8–49.5 Bq/kg with an average of 36.7 Bq/kg which is comparable to the global average of 35 Bq/kg.
