A low cost, rapid, flexible radiation detector uses inorganic metal halide precursors and dyes that respond to self-quenching hybrid scintillation. Remote, high-contrast, laser sensing can be used to determine when exposure of the detector to radiation occurs (even temporally).

Provided are a radiation measurement device and method that allow stable radiation measurement as compared with the prior art. The radiation measurement device includes a radiation detection unit 1 having a scintillator, an optical transmission member 21 for transmitting an optical signal generated in the radiation detection unit, and a signal processing unit 3 for calculating a radiation dose from the optical signal transmitted. The signal processing unit includes a compensation unit 7 for obtaining an optical transmission loss amount from a change in wavelength spectrum in the optical signal caused by radiation acting on the optical transmission member and performs compensation-control on the optical transmission loss amount, and outputs a compensated signal.

The present technology relates to a light-receiving device that makes it possible to simplify readout from a plurality of pixels and a process after the readout, without deteriorating light receiving sensitivity and characteristics in resolution. A plurality of unit elements is disposed above a substrate, each of the unit elements including a plurality of pixels disposed in m number of rows and n number of columns, and a readout section that sequentially reads out signals from a plurality of pixels disposed in a column direction among the plurality of pixels. The number of readout sections is at least the same as the number of columns. The readout section includes a QV amplifier. The present technology is applicable to the light-receiving device that detects radiation.
