Berthold - LB 147 Hand-Foot Monitor

Catalog No. 45356-10 Category

PERSONAL CONTAMINATION MONITOR

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.

LB 147

  • The LB 147 has a removable hand probe for clothing measurements
  • Innovative scintillation technology for radiation protection
  • Robust design
  • Removable hand probe for clothing measurement
  • No counting gas required
  • Simultaneous separate measurement of α and β-γ radiation
