FIELD: medicine.
SUBSTANCE: in order to detect hand traces, traces are processes with directed reagent flow, which makes traces visible. As reagent, used is ozone-air mixture with ozone concentration 30-50 mg/m3, flow of which is used to process hand traces. On dry surface processing with reagent is carried out for 10-30 seconds, on moist or wet surface - not longer than 3 minutes.
EFFECT: method increases quality of hand trace visibility.
