A silicon PIN diode (in this case an inexpensive off-the-shelf device designed for infrared optoelectronics), accompanied with appropriate electronics, can detect charged particle and energetic photon (X-ray or gamma-ray) impacts on the diode, allowing for basic qualitative ionising radiation counting (for educational use, for example) A silicon PIN diode (in this case an inexpensive off-the-shelf device designed for infrared optoelectronics), accompanied with appropriate electronics, can detect charged particle and energetic photon (X-ray or gamma-ray) impacts on the diode, allowing for basic qualitative ionising radiation counting (for educational use, for example)
