To processor 20；Processor 20 is connect at least one detector 10, for receiving electric signal, and to electric signal handled with
Obtain radiation data；Shielding part 40 is coated on the outside of cavity 30, for radiation-screening radioactive source background spoke in the scene
It penetrates, wherein at least one detector 10 between cavity 30 and shielding part 40, shielding part 40 includes at least two-layer screen layer,
At least two-layer screen layer is to be detachably connected.In Fig. 1, the position of detector 10 and processor 20 and cavity 30 and shielding part 40 is only
It is signal, does not represent true set-up mode.And detector 10 and processor 20 are surveyed with cavity 30 and shielding part 40 due to radiating
The shell for measuring equipment blocks, substantially sightless, for the ease of in the signal embodiment of the present invention or using solid line into
Row signal.
Since there are background radiations in measurement environment, so accurate Radiation emitting sources to be measured in order to obtain,
Such as similar to the small article of safety cap etc. amount of radiation when, need to shield background radiation.Specifically, the utility model is real
It applies in example, radiation-measurment equipment can be set one for placing the cavity 30 of small article, can be set in the outside of cavity 30
Multiple detectors 10, and the shielding part 40 being made of in the periphery setting of multiple detectors 10 multilayer screen layer, wherein shielding part
40 complete coating cavities 30.Since shielding part 40 is isolated by the small article being located in cavity 30 with the amount of radiation in environment, so that
Detector 10 influences the measurement of small article from background radiation, so that measurement result is more accurate.
In possible embodiment, as shown in Fig. 2, shielding part 40 may include at least two-layer screen layer 400, and at least two
Layer shielded layer 400 is to be detachably connected.When radiation-measurment equipment measures the spoke of small article in the lower scene of background radiation
When the amount of penetrating, then one layer therein or several layers of shielded layers 400 can be dismantled from least two-layer screen layer 400, to reduce shielding
The thickness of part 40 matches with the lower background radiation to be shielded.And when the article in the measurement higher scene of background radiation
Amount of radiation when, then one layer or several layers of shielded layers 400 can be further added by the basis of original shielded layer 400, with increase
The thickness of shielding part 40 matches with the higher background radiation to be shielded.In compared to the prior art, the shielding of fixed thickness

It is damaged at shielding part 40 either large area damage or portion, requires to replace entire shielding part 40, more
Waste.In the utility model embodiment, the shielding part 40 that multilayer screen layer 400 forms can only replace that layer of damage, section
About resource.
In possible embodiment, the overall thickness for at least two-layer screen layer 400 that shielding part 40 includes is located at [1cm, 5cm]
In range.The corresponding overall thickness of namely lower background radiation is normally at 1cm or so, overall thickness corresponding compared with High Background Radiiation
It is normally at 5cm or so.Certainly, the overall thickness for at least two-layer screen layer 400 that shielding part 40 includes can be according to different scenes
Background radiation amount determine, to improve the shield effectiveness to background radiation.
In the utility model embodiment, the thickness for at least two-layer screen layer 400 that shielding part 40 includes can be identical.Shielding
The material of layer 400 includes lead or other possible materials, then the heavier-weight of shielded layer 400.If every layer of shielded layer
400 it is thicker when, then replace or add or disassembly shielded layer 400 when it is more laborious.And if every layer of shielded layer 400 compared with
It is thin, then when measuring the article in the scene compared with High Background Radiiation, it may be necessary to add multiple shielded layer 400, more
It is cumbersome.In possible embodiment, the thickness of at least one layer of shielded layer 400 is less than or equal at least in two-layer screen layer 400
5mm, the lighter in weight of every layer in this way shielded layer 400 are conveniently replaceable or add.For example, the overall thickness requirement of shielding part 40 is
5cm, then shielding part 40 may include 10 layers of shielded layer 400, the thickness of every layer of shielded layer 400 is 5mm.
Certainly, the thickness of the shielded layer 400 for the multilayer that shielding part 40 includes can not also be identical, continues to use above-mentioned example,
If the overall thickness requirement of shielding part 40 is 5cm, shielding part 40 may include 8 layers of shielded layer 400, wherein 6 layers of shielded layer
400 thickness is 5mm, and in addition the thickness of 2 layers of shielded layer 400 is 1cm, to reduce replacement number to the greatest extent, while also to the greatest extent may be used
It can be laborsaving.
