Farmer-type Ionization Chamber with graphite walls, aluminium central electrode, vented, PMMA built-up cap, full-guarded, 2m low-noise cable, connector BNT (other type on request). Because of its excellent long-term stability and flat energy dependance, the chamber can be used as a part of REFERENCE DOSEMETER for transfer of dosimetry units from the SSDL.
For measurement in water phantom the rubber sheathMR 2911 is necessary.
MR 2102 is the watertight version of precision ionization chamber MR 2101.
The internal design of the ion.chamber body icluding the sensitive volume is identical with the MR 2101. The only difference is that the cable is going through the tube to enable free ventilation to the outer atmosphere.
MR 2102 is delivered with two caps :
The first one for measurement free in air is indentical to MR 2101 buid-up cap.
The second one for measurement in water is sealed with o-ring to the chamber body and the thickness at the sensitive volume is 1mm only.
ON REQUESTMR 2802 - Check Source Sr-90 (80MBq) » for the long-term stability tests of thimble ionization chambers
Check source MR 2802 is to be used for verification of the long-term stability of ionization chamber sensitivity.
Ionization chamber is placed inside the check source shielding container by means of the exchangeable adapter MR 2802A-*. This design makes possible to use the MR 2802 check source for various ionization chambers, while using an appropriate adapter. There is only one limitation - the outer diameter of the chamber must be smaller then 13 mm.
