Measurements of trace heavy metal at environmental samples by neutron activation method

Trace elements are released into the atmosphere from various sources and threaten human health. Neutron activation analysis is one of the method to determine the amount of matter of this trace elements. In this study, the least possible amount that can be detected of liquid and/or solid Cadmium (Cd), Antimony (Sb), Mercury (Hg), Bismuth(Bi), Lead (Pb), Tellurium (Te), Arsenic (As), and Tin(Sn) had been irradiated adequate flux values and adequate distance in reactor and the activity of samples had been measured by using gamma counting system.
