Berthold Model LB-124B, Beta-Gamma Contamination Monitor
Model LB-124B, Beta-Gamma Contamination Monitor
Measuring safely with one hand
The handheld beta-gamma contamination monitor LB 124 for the measurement of radioactive surface contamination is based on well proven high perfor- mance Xenon filled proportional counter technology.
This detection technique provides extremely high sensitivity for both, beta and gamma radiation. The instrument is therefore ideally suited for the measure- ment of photon emitting radio nuclides, widely used in nuclear medicine as well as in other laboratories environments.
The software offers many useful modes of operation, complex functions, utilities, and access to all para- meters for experienced users. For unskilled users the instrument's configuration can be defined in supervisor mode as a simple or even extremely simple system. The supervisor can grant access authorization for user profiles only for selected menus, functions or para- meters according to the special needs of the site. The instrument has a memory to store measured values and bi-directional serial RS232 communication. This provides program download, parameter download, remote control and data transfer to a host computer or printer.
The LB 124 is ergonomically designed and is easy to use. It has a low weight allowing real one hand operation for daily routine. The instrument has a large graphical display with background illumination facility. The results are always clearly indicated - even under bad conditions. Control of the instrument is easily done via simple multi-function keys.
The Advantages:
The 150cm2 detector measures beta and photon
radiation with highest counting efficiency, in particular
for EC emitters like I-125 or Tc-99m
The large, easy-to read backlit LCD display shows measured
results in cps or Bq/cm2 with factory defined, editable
calibration factors for more then 50 radionuclides
Powerful software supports numerous measuring modes and
parameter settings, for example: search, clearance measurement, half-life,
background measurement mode
The monitor is easily configured both from the unskilled user
and for the demanding measuring expert
The memory stores up to 1000 measurements with date/time
stamp. Data may be downloaded to a PC or printer via the RS232 interface
