Electron Spin Resonance

Used in electron beam and neutron dosimetry and many kinds of photon radiation dosimetry.

The material alanine is considered as tissue equivalent and widely used in dosimetry with Electron Spin Resonance (ESR or EPR). It is especially used in electron beam and neutron dosimetry but also for many kinds of photon radiation dosimetry.
