Clinical engineers and biomedical technicians play a vital role in bioterror preparedness because of their extensive expertise regarding new technology assessment. This article details a new technology for maintaining healthy indoor air quality in the event of a bioterror attack. 
The study examines 2 outcomes: (1) examination of a reduction of airborne microbial counts in specific clinical areas as a results of implementing the PCR unit in the clinical areas sampled (as identified in Tables 1-7) and (2) statistical evidence related to the cost-related savings due to lessened risk factors of lower microbial counts involving nosocomial and cross-infections. Healthcare economics and patient comfort will be impacted as a result, if lower airborne microbial colonies result from the implementation of the PCR biocide unit. A scientific explanation of the photocatalytic oxidation (PCO) process and the distinct uniqueness of the PCO and ultraviolet (UV) combination process (PCO) utilized by the PCR biocide unit will be examined in depth.
