Description

Abstract: 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
