Without context, the term "radiation" sometimes refers to any type of radiated energy, including radio waves, microwaves, and visible light.
Many dedicated alpha detectors overcome the very low penetration of particles by covering the detection medium with an extremely thin, delicate film.
Beta particles are simply electrons emitted from the nuclei of decaying radioactive isotopes, and as such they are negatively charged.
Gamma and x-rays are the easiest radiation types to detect due to their penetrative properties. Neutron radiation, as the name implies, involves the emission of neutrons from decaying atoms. Because neutrons do not cause ionization in the same way that other particles do, they typically require fairly specialized versions of common detection equipment. Scintillation detectors represent the best means for detecting gamma or x-radiation and are the second-most common detector type after G-M tubes. Solid state detectors are modern semiconductor instruments which use a reverse-bias p-n junction diode. Semiconductor detectors essentially operate in a similar manner to G-M tubes, except that the electrons and ions used as charge carriers in a gas detector are replaced by electrons and holes. Published standards which describe the calibration and use of radiation detectors are important due to the multitude of regulations restricting the amount of radiation in waste and the environment. Gamma-ray bursts are the result of the rapid collapse of high-mass stars, or a collision between binary neutron stars. The funny thing about gamma-ray bursts, however, is that at least one is observed every day. If, however, a gamma-ray burst occurred within the Milky Way Galaxy, and was aimed directly at Earth, it would be Lights Out for most, if not all, life on the planet. It’s possible that some deep-sea organisms would survive, shielded from the brunt of the radiation by the ocean waters.
First, we would likely see, with our naked eyes, an explosion out in space that would appear as bright as the sun. So, what we’re talking about here is a really, really, really bad day for all life on Earth. By ancient, I mean about 450 million years ago, during the Ordovician-Silurian extinction event. Our biggest threat today in regards to gamma rays are the World Rayet stars, which have been described as “ticking bombs” because they’re massive, hot, and rapidly losing mass. For now, we have satellites like NASA’s SWIFT hanging out in space, hunting for gamma-ray bursts and gathering information on these powerful cosmic death rays.

We define a gamma-ray burst based on its observational properties: an intense flash of gamma rays, lasting anywhere from a fraction of a second to up to a few minutes. Cosmic gamma ray bursts (GRBs) were discovered by accident in the late 1960’s by satellites designed to detect gamma rays produced by atomic bomb tests on Earth. A major leap forward in understanding the source of cosmic GRBs was made when the Burst and Transient Source Experiment (BATSE) was launched aboard the Compton Gamma Ray Observatory in 1991.


BATSE had an all-sky monitor that was capable of detecting a GRB virtually anywhere in the sky. As Gamma rays are electromagnetic radiation (photons), they travel with the speed of light.

It more commonly describes ionizing radiation, which ionizes contacted atoms by liberating electrons.
While this renders the device exceptionally fragile, it does compensate for alpha particle difficulties. As such, these particles have less penetrative power than alpha particles and are exceedingly difficult to detect. Due to the high ionization potential of alpha particles, G-M tubes are effective as alpha detectors. They consist of a salt crystal (most often sodium iodide), also known as a "scintillator", attached to a photomultiplier tube. As a particle passes through the junction, the resultant excitation of electrons causes the formation of holes in the valence band. Fixed detectors are typically used in laboratories and other testing facilities and are designed to sit on a tabletop or attach to a process stream.
If it were to happen at the right distance, and point in just the right direction, it would obliterate everything on Earth’s surface. Gamma rays alone are the strongest (highest frequency) and most dangerous form of electromagnetic radiation. In either case, gamma radiation shoots out in two distinct beams from the star, one at each pole, sending powerful, narrow streams of electromagnetic radiation shooting through space.
Even then, the depletion of the ozone layer would spell rough times ahead for anything left alive. While Earth’s atmosphere would initially protect the planet, it would be cooked fairly quickly, superheating the planet’s entire surface. It may have also already experienced a gamma-ray burst, leading to an ancient mass extinction event (yeah, we’ve missed all the cool stuff, right?). It’s theorized that the mass extinction of this time was caused by a gamma-ray burst, given an observed “pattern of higher UV radiation” found to correlate with that time period.
WR 104, in particular, sits a cool 8,000 light-years away, and is considered a “potential threat.” It’s a massive, binary star, and may be aligned in such a way that if it were to go supernova and produce a gamma-ray burst, we could be in serious trouble. He manages Stranger Dimensions in between changing aquarium filters and reading bad novels about mermaids. We believe them to be beamed - the energy does not escape from the explosion everywhere equally, but is focused into a narrow jet (or more likely, two oppositely-directed jets.) The burst itself is also normally followed by a much longer-lived (but also much fainter) signal, visible at optical and other wavelengths. The GRBs appear first as a brilliant flash of gamma rays, that rises and falls in a matter of minutes. The Website was developed in part with the support of UCAR and NCAR, where it resided from 2000 - 2010.


Because radiation cannot be naturally sensed by humans, radiation detectors are essential for monitoring radiation emissions from industrial, medical, and nuclear power facilities to ensure that emissions meet certain guidelines and regulations. Compared with other radiation particles, alpha types are heavy and incapable of travelling more than a few centimeters. Beta particles can penetrate thin materials, including paper and the outer layers of human skin, but typically cannot penetrate clothing. Neutrons are highly penetrative and can travel long distances, requiring thick, hydrogen-rich barriers comprised of water, concrete, or oil to be blocked. The electron is attracted to the electrified element and causes electrons from other argon atoms to become dislodged along the way.
They also have high sensitivity characteristics due to the electron "avalanche" which occurs after sensing even a single particle. When a radiation particle strikes the crystal, it causes excitation and the release of photons, resulting in a tiny flash of visible light. The electrons are then attracted to the n material, while the holes move toward the p material.
Bursts of these rays emit “more energy in a few seconds than our sun will during its entire energy-producing lifetime,” and a few seconds would be all it takes to decimate the Earth’s ozone layer and lead to an incredible mass extinction event.
Thankfully, all of those observed to date have occurred billions of light years away, well beyond the confines of our own galaxy, and the Milky Way itself doesn’t seem likely to produce any Earth-destroying bursts any time soon. Once the invisible, deadly beam from one of its poles shot toward us, even if we knew it was coming, it would simply be a matter of time. Beyond the initial effects, the gamma rays would potentially also bring about acid rain, lead to photochemical smog, which would darken the skies, which would unleash a terrific cosmic winter and, last but not least, expose Earth to harmful cosmic radiation. Otherwise, Planet Earth has already witnessed a plethora of doomsday scenarios, from supervolcanoes and (maybe) rogue planets to ice ages and asteroid impacts. The mainstream thought is that the event was instead caused by climate change, but gamma rays are still on the table. Among other things, these results showed that the bursts occurred at random all over the sky. When all the electrons arrive at the wire, a pulse forms which can be transmitted to a counter. The flash is reflected through a lens and makes contact with a photocathode, a specialized device which produces electrons when contacted by light. If the bursts were associated with objects in our Milky Way Galaxy, they would not show such a universal distribution. The electrons are pulled through a photomultiplier and are collected by an anode to form an electromagnetic pulse; this pulse is detected and displayed by a meter. Rather, they would be concentrated along the plane of our galaxy like most of the matter in the Milky Way. Scientists from the University of Cape Coast in Ghana webcast live video coverage of this event.
