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 ...
A monitor unit (MU) is a measure of machine output from a clinical accelerator for radiation therapy such as a linear accelerator or an orthovoltage unit. Monitor units are measured by monitor chambers, which are ionization chambers that measure the dose delivered by a beam and are built into the treatment head of radiotherapy linear accelerators.
Survey meters in radiation protection are hand-held ionising radiation measurement instruments used to check such as personnel, equipment and the environment for radioactive contamination and ambient radiation. The hand-held survey meter is probably the most familiar radiation measuring device owing to its wide and visible use.
Aware Electronics Corp. is a United States of America designer and manufacturer of radiation monitors and Geiger Counters. It is located in Wilmington, Delaware and was incorporated in 1986 [ 1 ] Aware's RM-80 detector with thin mica window pancake detector plugged into the LCD-90 microcontroller data-logger with Class 1 Bluetooth adapter ...

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 ...
