Radionuclides are used in many areas of research, nuclear medicine and natural sciences. Wherever open radioactive materials are handled, contamination measurements by hand, feet and clothing are required in accordance with radiation protection guidelines.

The Personal Contamination Monitors LB 147 and LB 148 are contamination monitors designed for use in the radiation protection field to detect contamination caused by alpha and beta/gamma radiation. Low-maintenance thin-layer ZnS (Ag) scintillators are used as detectors. The operation is via a touch panel on a graphical display.

Description
The LB 148 version has four automatically tracked hand detectors that allow both the palms and the back of the hands to be measured simultaneously. With the LB 147 version, an automatic prompt for back of hand measurement can be activated. The LB 147 is also available in a narrow version LB 147 Slim with a different positioning of the hand detectors. There are two variants: the detectors are facing the user (ID 45356-15) or the detectors are facing away from the user (ID 45356-18). The LB 147 and LB 148 are also available as an Alpha Sense version with special modification of the protective grid for lower α-detection limits. All monitor versions have a detachable probe for clothing measurements.
