D3S isotope library
Library far exceeds ANSI and international standards
- 42 isotopes – 22 more than ANSI N42.34 standard.
- Discriminates between Medical, NORM, Industrial and SNM classes.
- 69 unique signatures which account for shielding and mixed configurations.
- Detection variation with distance for Caesium-137 at 50 μR/h (0.5 μSv/h) meets ANSI 42.34.
Detection ID probability ≥ 90% at over 12 meters (39.3 feet or 13 yards) against nominal source activities.
