Classification: CPC G  H | IPC G  H

Claim 16:
17. A radiation detection method that employs a radiation detection device that includes a memory chip including a plurality of non-volatile memory cells, said method comprising:
while power is supplied to the radiation detection device, erasing all of the non-volatile memory cells of the memory chip;
cutting off the power supplied to the radiation detection device after having erased all of the non-volatile memory cells of the memory chip;
while power to the radiation detection device is cut off and while all of the non-volatile memory cells of the memory chip are in an erased state, placing the radiation detection device in a gamma ray detection area for a period of time;
after the period of time has elapsed, re-supplying the power to the radiation detection device and detecting gamma rays incident on the radiation detection device according to a data inversion or a threshold voltage change of at least some of the non-volatile memory cells in the memory chip.
