Optimization of firearm residue detection by neutron activation analysis.

An investigation of the chemistry and radiochemistry involved in firearm discharge residue detection has been carried out. The usefulness of internal standards was demonstrated. The details and pitfalls were pointed out for the benefit of the novice worker planning to acquire neutron activation analysis capability. We hope that this investigation will receive constructive criticism from the experienced workers in the field and hopefully serve as the beginning of a uniform radiochemical procedure for the detection of firearm residue.
