Personal Alarming Dosimetry

The personal alarming dosimeter is designed to be worn on the chest and measure the Hp(10) dose (and in some cases the Hp(0.07) dose) absorbed by the individual. The dosimeter displays the dose and dose rate, and will alarm if pre-set thresholds for either are exceded. They are used as an operational tool to manage the dose-uptake to individuals both on-the-job and on a day-to-day basis.

The MGP Instruments robust and reliable DMC 2000 series feature pass-by data exchange which in combination with a comprehensive range of fixed and portable dosimeter readers gives unequal operational flexibility. Software packages for managing the dose information can be configured to suit the requirements of the customer. The dosimeters feature a flat energy-response to both X-rays and gamma radiation, with some versions also measuring surface dose or neutrons.
