Personal Monitors

The use of radioactive materials can cause radioactive contamination spots in buildings and working areas. An important task of Health Physics is to prevent spread of contamination to other work areas, in particular out of controlled areas. Contamination itself can be carried by workers on their clothes, tools and even on their bodies. Personal body monitors mainly concerns the checking of people before they enter or leave an area, building or site. Their typical deployment is at the boundaries between controlled and clean areas.
