Ionization chamber and measuring system for low-level dosimetry

Natalia Golnik , Z. Rusinowski , M. Zielczynski


A system for low-level dosimetry is proposed, It contains a recombination chamber with specially designed electronic circuit. Polarizing electrodes of recombination chamber of REM-2 type are supplied from capacitors permanently connected to the electrodes. Ions, collected on the measuring electrode, charge a measuring capacitor that is also permanently connected to the electrode. The special procedure was introduced for charging the supplying capacitors and for reading the voltage on the measuring capacitor. The chamber can be used in saturation mode, when the collected charge is proportional to the absorbed dose, or in differential mode for determination of the ambient dose equivalent, H*(10). Experimental tests indicated that the measuring system with the REM-2 chamber allows measuring the H*(10) above 10 mu;Sv with uncertainty ca. 25\% in any field of penetration radiation, with an integration time up to several days
