Chemical, biological, radiological, and nuclear weapon detection system with alarm thresholds based on environmental factors
First Claim
1. A system comprising:
- a first environmental sensor for monitoring a first environmental characteristic;
a first hazardous material sensor for measuring the amount of a first hazardous material; and
a first alarm that is issued when the amount of said first hazardous material reaches a first threshold, wherein said first threshold changes and is based on said first environmental characteristic.

Abstract
A chemical, biological, radiological, and nuclear weapon detection system is disclosed that incorporates a mechanism to reduce the probability that a false alarm will be issued. In particular, the mechanism causes an alarm to be triggered when the amount of a hazardous material reaches a threshold, but changes the threshold based, at least in part, on environmental (e.g., meteorological, etc.) characteristics (e.g., whether is it precipitating or not, whether it is sunny or not, etc) that effect the efficacy of a chemical, biological, radiological, or nuclear weapon. Given that there are environmental factors that make an attack less effective, and given that terrorists are aware of this, the illustrative embodiment is less likely to issue an alarm when the environmental factors suggest that an attack is less effective, and, therefore, less likely. The illustrative embodiment accomplishes this by changing the threshold needed to issue an alarm based on one or more the environmental factors.
