How do we detect gamma rays?. - [PPT Powerpoint]

WebWe were working with high-frequency sound waves in tissue samples and found we could detect approximate density of samples in a short range by looking at the returning pulses. "This is great, we could use it to remotely sense-- oh goddamnit this is exactly how ultrasound scanners work isn't it." ... A related device using gamma rays, so ... WebA gamma ray, also known as gamma radiation (symbol γ or ), is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei.It consists … WebA quantity used to indicate the amount of ionization in air produced by x- or gamma-ray radiation. The unit is the roentgen (R). For practical purposes, one roentgen is comparable to 1 rad or 1 rem for X ray and gamma radiation. The SI unit of exposure is the coulomb per kilogram (C/kg). One R = 2.58 x 10-4 C/kg. Gamma rays, or gamma radiation tinkerbell if you have to choose
