The calibration source comprises a radioactive material (30) comprising a radioactive isotope having a decay transition associated with emission of a radiation particle and a gamma-ray having a known energy, e.g.Na-22, and a solid-state detector (26A, 26B), e.g. a PIN photodiode, arranged to receive radiation particles emitted from thE radioactive material.
