Description
Technical field
The utility model relates generally to detector field more particularly to a kind of diamagnetic flash detector probe.
Background technique
Detecting head crystal often uses NaI sodium iodide or LYSO yttrium luetcium silicate in all kinds of existing radiation source detectors, using iodate
Sodium, crystal needs to be closed with metal, such as aluminum hull, and needs damp-proof treatment, therefore cannot detect metal, adaptability
It is small；Using yttrium luetcium silicate, crystal needs to use background, has certain limitation for spoke monitoring.In addition, commonly radiating source detection
In machine, photomultiplier tube is used after crystal, but since photomultiplier tube does not have diamagnetic performance, is led to not under strong magnetic environment
It uses.
