  • Title: Assessment of radiological significance of naturally occurring radionuclides in soil and rock matrices around Kakrapar environment.
    Author: Patra AK, Jaison TJ, Baburajan A, Hegde AG.
    Journal: Radiat Prot Dosimetry; 2008; 131(4):487-94. PubMed ID: 18658174.
    Abstract:
    The activity and gamma-absorbed dose rate due to the naturally occurring radionuclides in the terrestrial environment such as (238)U, (232)Th and (40)K were determined in soil and rock samples collected around Kakrapar Atomic Power Plant site, using gamma-ray spectrometry. The mean concentration levels measured in Kakrapar soil from naturally occurring radioisotopes such as (238)U, (232)Th and (40)K are lower than the corresponding global average values obtained in worldwide soil. The external hazard index (H(ex)) and absorbed gamma dose rate in air outdoors is observed to be 0.04-0.18 and 3.1-14.1 nGy h(-1), respectively.
