Automation System for Tritium Contaminated Surface Monitoring

Abstract

The low energy of betas makes tritium difficult to detect. However, there are several methods used in tritium detection, such as liquid scintillation and ionization chambers.

Tritium on or near a surfe can be also detected using proportional counter and, recently, solid state devices.

The paper presents our results in the design and chievement of a surface tritium monitor using a PIN photodiode as a solid state charged particle detector to count betas emitted from the surface. That method allows continuous, real-time and non-destructively measuring of tritium.
