Features
- Vented sensitive volume of 10 cm3
- Measures the H p (10) personal dose equivalent directly
- Suitable as a reference chamber for H p (10) calibration
The parallel plate ionization chamber model 340351 is integrated into a slab phantom to measure the H p (10) radiation protection measuring quantity directly. The high performance chamber is designed to be used as a secondary standard chamber for calibration purposes. The beam calibration with the H p (10) chamber makes it unnecessary to precisely determine the spectrum of the X-ray beam. The chamber comes uncalibrated; a primary standard calibration by PTB, the German National Laboratory, is available. The useful gamma energy range is from 10 keV to 1400 keV. The chamber response is approx. 350 nC/Sv. The chamber set includes a phantom slab of 31 mm thickness with chamber assembly and an additional phantom slab of 120 mm thickness. The slab phantom is composed of tissue-equivalent acrylic material (PMMA). The total external dimensions are 300 mm x 300 mm x 151 mm. Both sets include an adapter cable to connect the chamber either to a dosemeter with M connector or with BNC connector and banana pin. The H p (10) chamber should be used in connection with a high quality dosemeter such as UNIDOS or UNIDOS E to ensure best performance.
