To investigate the present situation of inhabitants living in the cadmium polluted area of Toyama Prefecture of Japan, 95 hair samples were analyzed by neutron activation method. The median and the geometric standard deviation were determined from a cumulative frequency distribution curve of the elemental concentrations for each of 3 groups: male, female without perm and female with perm which were divided furthermore by two age ranges: 20 age<50 and 50 age. These concentrations were compared with those in some organs and urine reported.
