The LB 124 B beta-gamma contamination monitor is used for the measurement of radioactive contamination on surfaces is based on the well-proven Xenon filled proportional counter technology. This detection technique provides extremely high sensitivity for beta particles and also for gamma radiation. The instrument is therefore ideally suited for the measurement of photon emitting radionuclides as widely used in nuclear medicine as well as in other laboratories and environments.

Applications
The contamination monitor LB 124 B is a versatile and flexible instrument for practical radiation protection. It can be employed wherever contamination caused by radioactive substances is encountered and has to be monitored: in nuclear medicine, research, nuclear power plants, in decommissioning of nuclear facilities, disposal of nuclear waste and also in environmental monitoring. The instrument is used to measure radioactive beta-gamma contaminations on surfaces such as floors, walls, desks, objects, clothing or skin.

Description
The contamination monitor LB 124 B is a portable battery-operated instrument with a sensitive area of 150cm². It comprises a sealed Xenon filled proportional counter tube, a microprocessor board with a display unit, as well as an amplifier and discriminator module with a high voltage supply for signal processing. There are guides to mount an additional grating for better detector protection or to use a sample holder with a drawer for activity measurement of small samples.
