Portable Gamma and X-ray Doserate Meter/Dosimeter [Babyline 81]

 

The BABYLINE 81 is a linear response doserate meter/dosimeter for measuring the dose rate and the absorbed dose in human tissues (under 0.007 g/cm2 or 0.3 g/cm2) for an irradiation by incident or scattered photons in the 8 keV to 10 MeV energy range and, occasionally, by electrons.

The unit comes in a case containing the high-gain-current amplifier and the processing electronic circuits. The unit is provided with a handle that holds the rechargeable or non-rechargeable batteries; the ionization chamber and its 0.3 g/cm2 removable cap are fixed on this case.

Several switches are provided to start the unit, to check the zero adjustment of the galvanometer and to select the measurement range (six dose rate ranges and five integrated dose ranges).

The large-sized needle indicator allows an easy reading of the absorbed dose rate. The presentation of the unit as a pistol facilitates its use.

The BABYLINE 81 has become the reference doserate meter in laboratories and nuclear facilities all over the world.
