Method and apparatus for determining hazard levels of chemical/bioligical/nuclear agents in an environment

A system and method for determining hazard levels of chemical, biological, and nuclear agents in an environment processes chemical vapor concentration measurements and generates hazard levels of the chemical vapor. The system and method provide an estimate of hazard level values by using an exponentially weighted moving integration of the vapor concentrations. When estimated hazard level values match or exceed empirically predetermined hazard accumlutaed dosage values for a particular chemical, biological, or nuclear agent, an indication of the level of hazard is generated.
