Lead shielding
The sampling and measuring slot is housed in a lead shielding block.
External gamma-ray background is attenuated by at least one order of magnitude.
Air flow pump
The nominal volume rate of the maintenance-free pump is 3.5 m©ø/h.
The output is measured indirectly by pressure sensor and temperature sensor.
The output rate is converted in ¡°normal cubic metre¡± (20¡ÆC, 1 bar pressure).
All activity values are related to this value (in Bq/m©ø).
Computer
Pulses from the continuously operating detectors are processed by multi channel analyser cards
with an effective channel range of 1k.
All of these cards are Microcontroller cards which are controlled by an Industrial PC over an RS422 Interface.
Also available with Lanthan-Bromid (LaBr3)instead of NaI detector
