X-Ray Area Dosimeter

The 451P was initially developed to assess leakage and scatter in the vicinity of diagnostic X-ray and radiation therapy suites. However, its radiation measurement surveying capabilities render it suitable for a diverse array of end users, such as X-ray manufacturers, government agencies, state inspectors, biomedical technicians, and maintenance technicians for airport baggage scanners.input:

output:
Simultaneous high-sensitivity μR measurements of rate and dose, with the ability to record the peak dose rate

A tripod mount, wrist strap, and ergonomic, anti-fatigue handle with a replaceable grip

An audible alarm and a programmable flashing LCD display

Battery door that is easily accessible and is operated by one or two 9-volt alkaline batteries is located on the exterior of the bottom case…

Optional Windows-based Excel add-in for data logging with RS-232 communications interface

Available with an ambient dose equivalent energy response (SI units)CE-certified. Satisfies the relevant standards.
The auto-ranging 451P ion chamber radiation survey meter is equipped with a pressurized ionization chamber, which allows for the measurement of radiation rate and dose from X-ray and gamma sources with improved energy response and enhanced sensitivity (µR resolution).The ion chamber detector enables a rapid response to radiation from leakage, scatter beams, and pinholes. Furthermore, the ionization chamber bias supply, which is low in noise, enables a rapid settling time of the background.input:
output:The digital display is equipped with an analog bar graph, a 2.5-digit digital readout, low battery and freeze (“peak hold”) mode indicators, and an automatic backlight function. An ON/OFF button and a MODE button are the components of user controls.
