text: Gamma rays were first detected from astronomical sources in the 1960s, and gamma-ray astronomy is now a well-established field of research.
text: Because of the increased wall thickness required to withstand this high pressure, only gamma radiation can be detected.
text: This improved understanding led to two major improvements: gamma-rays that had been missed by previous analysis were detected and the direction they arrived from was determined with greater accuracy.
text: Gamma-rays are detected by observing the effects they have on matter.
text: The energy of the gamma rays being detected is an important factor in the efficiency of the detector.
