Radiation Detectors

Proportional Counters

Below information is purpose for of development, design and production of industrial inspection systems by implementing our company's products. Technical and regulatory confirmation/verification is necessary before purchasing and using of these products.

An X-ray proportional counter (PC) is a detector that makes use of the ionization effect of X-rays on an internal gas that may be either xenon or neon (for low energy X-rays). Its signal can be amplified by applying a high voltage to the center electrode. A pulse-height signal proportional to the energy of the X-rays applied can also be obtained.

PCs are suitable for measuring thickness of metal plating.

Proportional Counter

Features

Long life and high stability

Chemical cleaning and high-temperature exhausting under vacuum condition on the detector completely eliminates impurities.Strict management of the filler gas.

Improved shock resistance
