摘要 |
The present invention relates to a radiation-detecting device and an associated detection method. The detection device includes a scintillation crystal and an avalanche photodiode. The surface of the scintillation crystal is coated with a high-reflection layer. When ionizing radiation irradiates the scintillation crystal, the crystal emits luminescence, which passes through or is reflected by the high-reflection layer at least once within the scintillation crystal before it is received by the avalanche photodiode, generating a detection signal.
