No Chance for
Radioactive Contamination
Radionuclides are needed and useful in many fields of
application. However, they may also be dangerous if
improperly handled. Therefore working with radioactive materials in Nuclear Medicine, Research or in

other fields of radionuclide applications requires continuous monitoring to detect possible contamination
of surfaces and objects in working areas, as well as on
clothes and on exposed skin.
If you need a portable instrument for monitoring
surface contamination, we offer three product
families: The handheld monitors LB 122 or LB 124
for single-hand operation with built-in large-area
detectors or the versatile LB 123 UMo system with
externally connected contamination detectors.
To detect possible contamination of personnel,
the Hand Foot Monitors LB 145 and LB 146 are

facilities, the Floor Monitors LB 165 and LB 166
are available to reliably assess widespread
contaminations.
