H_p (10) Secondary Standard Chamber Type 34035

• 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 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 H_p(10) chamber should be used in connection with a high quality dosemeter such as UNIDOS, UNIDOS E or UNIDOS^webline to ensure best performance.
