Present study is an attempt to assess the radioactivity level and thereby obtaining the radiological parameters in and around the Rajapuram cashew plantation, an endosulfan spread area, Kasaragod in order to understand the associated health risk to the residents of the area. The external gamma radiation survey has been carried out using a sensitive portable plastic scintillometer (UR-705). The radiological parameters viz. absorbed dose rate (D), annual effective dose rate (indoor & outdoor), and excess lifetime cancer risk (ELCR) were calculated, compared with the reported values elsewhere and possible conclusions are drawn. The values of radiological parameters are well within the permissible limits except the annual effective dose rate (indoor). The study clearly indicates that, the potential carcinogenic effects and the probability of occurrence of cancer to the inhabitance due to gamma radiation exposure is insignificant. The results of these systematic investigations are presented and discussed in detail in the manuscript.
