Examples of products that CDRH regulates include medical devices ranging from tongue depressors and personal protective equipment (PPE) to pacemakers and robotic surgical systems, and medical and non-medical radiation-emitting electronic products such as lasers, x-ray systems, ultrasound equipment, microwave ovens, and color televisions.
Examples are installed "area" radiation monitors, Gamma interlock monitors, personnel exit monitors, and airborne particulate monitors. The area radiation monitor will measure the ambient radiation , usually X-ray , Gamma or neutrons; these are radiations which can have significant radiation levels over a range in excess of tens of metres from ...
To monitor gamma rays or x-rays, the filters are metal, usually lead, aluminum, and copper. To monitor beta particle emission, the filters use various densities of plastic or even label material. It is typical for a single badge to contain a series of filters of different thicknesses and of different materials; the precise choice may be ...
The personal ionising radiation dosimeter is of fundamental importance in the disciplines of radiation dosimetry and radiation health physics and is primarily used to estimate the radiation dose deposited in an individual wearing the device. Ionising radiation damage to the human body is cumulative, and is related to the total dose received ...
An example of the CD V-715 survey meter. By far the most common US civil defense meter on the market today. This is a simple ion chamber radiological survey meter, specifically designed for high-radiation fields for which Geiger counters will give incorrect readings (see above). Survey meters do not read alpha or beta radiation.
A damaged dialysis device. A busted hearing aid. A roughed-up cancer patient. These allegations are included in a federal lawsuit filed this week against a Texas police department accused of ...

Radiation monitors in general have a number of process-control applications in nuclear power plants; [9] a major CPAM application in this area is the monitoring of the air intake for the plant control room. In the event of an accident, high levels of airborne radioactivity could be brought into the control room by its HVAC system; the CPAM ...
