Introduction:

The Ludlum Model 23 Mrem Electronic Personal Dosimeter is a compact and lightweight pen-type personal dosimeter. It is ideal for the measurement and general monitoring of gamma and X-ray radiation in medical and laboratory environments, as well as any controlled or restricted area where personal radiation monitoring is required or desired.

The Ludlum Model 23 unit is sensitive to a wide range of energies from 35 keV to 3 MeV. Dose, Dose Equivalent Rate, and alarm values are easily seen on the four-digit LCD screen. An audible alarm is activated if the dose or dose rate exceeds the pre-set value of the dosimeter. The alarm set points are adjustable from the face of the Electronic Personal Dosimeter (EPD) unit.

Warning: this dosimeter may not measure pulsed radiation accurately.

For users with multiple EPD units the optional Ludlum Model 23 Mrem Reader/Software Kit can be used to quickly take data directly from the dosimeter via infrared communication to the user’s PC. The software also allows the user to set or change alarm set points quickly.
