In this paper we consider a network where an intruder is moving “contaminating” the nodes it passes by, and we focus on the problem of decontaminating such a network by a team of mobile agents. The contamination/decontamination process has the following asynchronous dynamics: when the team is deployed all nodes are assumed to be contaminated, when an agent transits on a node, it will clean the ...

Summary: We developed an SnO2 nanowire network visible-blind ultraviolet (UV) photodetector for applications in fields such as safety systems, exposure control, and decontamination processes, among others [...]

The objective of the present study is to evaluate the cost and effectiveness of decontamination strategies in the special decontamination areas in Fukushima in regard to external radiation dose. A geographical information system (GIS) was used to relate the predicted external dose in the affected areas to the number of potential inhabitants and the land use in the areas. A comprehensive review ...

In this article, we analyze feedback from simulated casualties who took part in field exercises involving mass decontamination, to gain an understanding of how responder communication can affect people's experiences of and compliance with decontamination. We analyzed questionnaire data gathered from 402 volunteers using the framework approach, to provide an insight into the public's experiences...

Following a CBRN incident, first responders use decontamination procedures to reduce the risk of exposure. The effect of decontamination on forensic trace material has, however, not been fully examined. This study sought to evaluate the effect of five different physical or chemical decontamination materials on the recovery of latent fingerprints. Fingerprints were deposited on glass slides, dec...

The efficacy of currently available decontamination strategies for the treatment of indoor furnishings contaminated with bioterrorism agents is poorly understood. Efficacy testing of decontamination products in a controlled environment is needed to ensure that effective methods are used to decontaminate domestic and workplace settings. An experimental room supplied with materials used in office...

Consider a tree network that has been contaminated by a persistent and active virus: when infected, a network site will continuously attempt to spread the virus to all its neighbours. The decontamination problem is that of disinfecting the entire network using a team of mobile antiviral system agents, called cleaners, avoiding any recontamination of decontaminated areas. A cleaner is able to de...

Although the principles of pediatric decontamination are similar as those for adults, the actual practice is much more challenging. The unique needs and vulnerabilities of children will require health care personnel to be sensitive to developmental stages of the victims and physiological hazards during decontamination. Unless medically indicated, families should undergo decontamination together...

Due to an increase of the nuclear power plant, radioactive waste is also increasing trend and due to the large amount of radioactive waste disposal costs also increase. Decontamination of soil contamination is depending on the soil characteristics and environmental factor, so single decontamination method is difficult for effective decontamination. We need innovative method to decontamination, ...
