Hp (10) Secondary Standard Chamber Type 34035
Plane-parallel ionization chamber for direct measurement of Hp(10) personal dose equivalent on a slab phantom
- Vented sensitive volume of 10 cm³
- Measures the Hp (10) personal dose equivalent directly
- Suitable as a reference chamber for Hp (10) calibration
The parallel plate ionization chamber model 340351 is integrated into a slab phantom to measure the Hp(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 Hp(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 chamber set includes a phantom slab of 31 mm thickness with chamber assembly and an additional PMMA phantom slab of 120 mm thickness. Both sets available include an adapter cable to connect the chamber either to a dosemeter with M connector or with BNC connector and banana pin.
The Hp(10) chamber should be used in connection with a high quality dosemeter such as UNIDOS, UNIDOS E or UNIDOSwebline to ensure best performance.
