First claim

What is claimed is:

1. A device of detecting a ray dose adaptable for coupling with a terminal, comprising:
a housing having an accommodating space and a window, wherein the accommodating space is in communication with the window;
a scintillator configured to receive a ray and convert a received ray into a visible light, wherein the scintillator is located in the accommodating space, the scintillator covers the window, an outer surface of the scintillator comprises a first outer surface and a second outer surface, and the first outer surface is adapted to a camera of the terminal; and
a light shielding layer configured to shield a visible light in an external environment from illuminating on the scintillator, wherein the light shielding layer is arranged on the second outer surface of the scintillator,
wherein the device of detecting a ray dose is mountable on the terminal, so that the scintillator and the window exactly face the camera of the terminal, so as to convert the ray in the external environment into the visible light adaptable for being received by the camera of the terminal,
wherein the device further comprises a light shielding pad configured to shield the visible light in the external environment from illuminating on the scintillator, and
wherein the light shielding pad is arranged between the housing and the scintillator.

2. The device according to claim 1 , wherein a light reflecting layer is further arranged between the second outer surface of the scintillator and the light shielding layer, and the light reflecting layer is configured to reflect the visible light converted by the scintillator.

3. The device according to claim 1 , wherein the housing and the scintillator are integrally arranged.

4. The device according to claim 1 , wherein the housing and the scintillator are separately arranged.

5. The device according to claim 1 , wherein the terminal comprises a mobile phone, and the housing comprises a mobile phone shell.

6. A method of detecting a ray dose, comprising:
triggering, in response to the device of detecting a ray dose adaptable for coupling with a terminal according to claim 1 converting a ray in an external environment into a visible light adaptable for being received by a camera of the terminal, a light-sensing component of the camera of the terminal; and
determining a ray dose value according to light data detected by the light-sensing component.

7. The method according to claim 6 , further comprising:
determining, in response to determining the ray dose value, corresponding time data, and corresponding position data and corresponding angle data of the device of detecting a ray dose;
determining regional ray dose data of a coverage region of each device of detecting a ray dose adaptable for coupling with a terminal, according to a ray dose value detected by each device of detecting a ray dose adaptable for coupling with a terminal.

8. The method according to claim 7 , wherein the regional ray dose data comprises:
regional ray dose intensity data of the coverage region, and regional ray dose intensity rheological data of the coverage region.

9. The method according to claim 6 , further comprising:
collecting, in response to determining the ray dose value, image data by using the camera of the terminal; and
determining a ray source according to the ray dose value and the image data.

10. The method according to claim 6 , further comprising:
comparing the ray dose value with a detection threshold value to determine an abnormal ray dose value; and
re-evaluating the abnormal ray dose value.

11. The method according to claim 6 , further comprising:
calibrating a ray dose value of an environmental background.
