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.
