“…For highly-ionizing particles the saturation voltage, see figure 1, from where on all charges are collected and thus the columnar recombination losses are negligible, will be element-and energydependent. This will lead to a characteristic I -V plot and this principle is presently used in modern dosimetry detectors called recombination chambers [8].…”

“…This decreases to 1.5x10 5 ion -e pairs per cm at 10 MeV and to 4x10 4 ion -e pairs per cm at 10 keV (here we take electronic and nuclear stopping). Taking some typically value of 8x10 4 ion -electron pairs per cm leads to a density along the track of one Rh ion of 8x10 8 ion-e pairs/cm 3 .…”

“…Recombination chamber of REM-2 type [22] contains 25 parallel-plate tissue-equivalent electrodes, with a total mass of 6.5 kg. The effective wall thickness of the chamber is equivalent to about 1.8 cm of tissue and the gas cavity volume is of about 2000 cm 3 .…”

“…The amount of recombination is related to linear energy transfer (LET), so also to radiation quality [21]. This property can be used for the determination of dose-equivalent quantities [22]. Recombination chambers are specially suitable for beam dosimetry and workplace measurements at high-energy accelerators, because of relatively fl at energy response of the instrument over whole neutron energy range and linear response in pulse radiation fi elds even at high dose rates [23][24][25][26].…”

Abstract. This work presents recombination methods used for secondary radiation measurements at the Facility for Proton Radiotherapy of Eye Cancer at the Institute for Nuclear Physics, IFJ, in Krakow (Poland). The measurements of H*(10) were performed, with REM-2 tissue equivalent chamber in two halls of cyclotrons AIC-144 and Proteus C-235 and in the corridors close to treatment rooms. The measurements were completed by determination of gamma radiation component, using a hydrogen-free recombination chamber. The results were compared with the measurements using rem meter types FHT 762 (WENDI-II) and NM2 FHT 192 gamma probe and with stationary dosimetric system.

“…H* (10) can be determined, without analysis of the radiation composition and spectra, by measuring D* (10) and Q*, using a detector which simulates the ICRU sphere. Recombination chamber of REM-2 type [5] is an example of such detector.…”

The work deals with the problem of the ambient dose equivalent measurements in high energy neutron fields by means of recombination ionization chamber. The method is based on the measurements of the absorbed dose and the recombination index of radiation quality Q 4r The chamber specific correction factor g(Q 4r ) was introduced in order to account for different neutron spectra. The correction factor depends only on the measured value of Q 4r and substitutes for other corrections. The relationship between g and Q 4r was established experimentally by the measurements in monoenergetic reference neutron radiation fields and in stray high energy radiation fields at CERF facility in CERN, at highenergy proton accelerator and in the maze of the carbon ion therapeutic beam at GSI in Darmstadt (Germany). The accuracy of the measurements is estimated to about 20%.
