Electronic Personal Dosimeter Model 23 (mrem)


The Ludium Model 23 Electronic Personal Dosimeter is a compact and lightweight pen-type personal dosimeter. Ideal for measurment 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 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 preset value of the dosimeter. The alarm set points are adjustable from the face of the unit. 


For users with multiple EPPD units, the optional 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 the alarm points quickly. 


WARNING: This dosimeter may not measure pulsed radiation accurately



Indicated Use: Dosimetry monitorintg of personnel

Dose and Dose Rate Measurement Display Range: 0.1 mrem to 99.99 rem (0.001 mSv to 999.9 mSv), 0.1 mrem/hr to 99.99 rem/hr (0.001 mSv/h to 999.9 mSv/h). Accumulated dose data is automatically deleted when the EPD is switched "On".
