Abstract

To provide an electromagnetic wave radiation detection member, an electromagnetic wave radiation detection method, and a device including the electromagnetic wave radiation detection member that make it possible to determine whether an object to be detected has been heated by electromagnetic wave radiation by a microwave oven or the like. One embodiment includes a detection material 1 containing liquid and discoloring a substance to be attached to which the detection material adheres, and a bag 2 including the detection material 1 therein and from which the liquid flows out due to radiation of electromagnetic waves. Accordingly, the substance to be attached is discolored due to electromagnetic wave radiation, thereby making it possible to determine whether the electromagnetic waves have been radiated.

Claims (24)

1. An electromagnetic wave radiation detection member comprising:

a detection material containing liquid and a substance that discolors that is attached to the detection material; and

a bag including the detection material therein and from which the liquid flows out due to radiation of electromagnetic waves.

2. The electromagnetic wave radiation detection member according to claim 1 , further comprising the liquid flowing out of the bag is adhered to the substance.

3. The electromagnetic wave radiation detection member according to claim 2 , wherein the substance comprises a test paper that is discolored when the liquid adheres to the test paper.

4. The electromagnetic wave radiation detection member according to claim 2 , wherein the substance comprises a base material contained in the bag with a hole, and the liquid flows out of the hole due to radiation of electromagnetic waves.

5. The electromagnetic wave radiation detection member according to claim 4 , wherein a transparent cover covering the hole is attached to the base material.

6. The electromagnetic wave radiation detection member according to claim 2 , wherein the substance has air permeability and water repellency.

7. The electromagnetic wave radiation detection member according to claim 1 , further comprising a waterproof container sealing the bag and the substance.

8. The electromagnetic wave radiation detection member according to claim 1 , wherein the liquid is included in the bag with a powder-like or gel-like substance.

9. A device to which the electromagnetic wave radiation detection member according to claim 1 is attached.

10. An electromagnetic wave radiation detection method comprising:

allowing a detection material comprising liquid to flow out from a bag due to electromagnetic wave radiation; and

attaching a substance that discolors to the detection material that flows out from the bag.

11. The electromagnetic wave radiation detection member according to claim 3 , wherein the substance has air permeability and water repellency.

12. The electromagnetic wave radiation detection member according to claim 4 , wherein the substance has air permeability and water repellency.

13. The electromagnetic wave radiation detection member according to claim 5 , wherein the substance has air permeability and water repellency.

14. The electromagnetic wave radiation detection member according to claim 2 , further comprising a waterproof container sealing the bag and the substance.

15. The electromagnetic wave radiation detection member according to claim 3 , further comprising a waterproof container sealing the bag and the substance.

16. The electromagnetic wave radiation detection member according to claim 4 , further comprising a waterproof container sealing the bag and the substance.

17. The electromagnetic wave radiation detection member according to claim 5 , further comprising a waterproof container sealing the bag and the substance.

18. The electromagnetic wave radiation detection member according to claim 6 , further comprising a waterproof container sealing the bag and the substance.

19. The electromagnetic wave radiation detection member according to claim 2 , wherein the liquid is included in the bag with a powder-like or gel-like substance.

20. The electromagnetic wave radiation detection member according to claim 3 , wherein the liquid is included in the bag with a powder-like or gel-like substance.
