In gamma-ray astronomy, gamma-ray bursts (GRBs) are immensely energetic explosions that have been observed in distant galaxies, being the brightest and most extreme explosive events in the entire universe, [1][2][3] as NASA describes the bursts as the "most powerful class of explosions in the universe".

Acute radiation syndrome (ARS), also known as radiation sickness or radiation poisoning, is a collection of health effects that are caused by being exposed to high amounts of ionizing radiation in a short period of time. [1] Symptoms can start within an hour of exposure, and can last for several months. [1][3][5] Early symptoms are usually ...
Into the Night is a Belgian apocalyptic science fiction drama thriller television series created by Jason George, inspired by the 2015 Polish science fiction novel The Old Axolotl by Jacek Dukaj. [1][2] The series premiered on Netflix on May 1, 2020. [3] It is Netflix's first Belgian original series. [4]
English. The Effect of Gamma Rays on Man-in-the-Moon Marigolds is a 1972 American drama film produced and directed by Paul Newman. The screenplay by Alvin Sargent is based on the Pulitzer Prize -winning 1964 play of the same title by Paul Zindel. Newman cast his wife, Joanne Woodward, and one of their daughters, Nell Potts, in two of the lead ...
A gamma ray, also known as gamma radiation (symbol. γ. ), is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei. It consists of the shortest wavelength electromagnetic waves, typically shorter than those of X-rays. With frequencies above 30 exahertz (3 × 1019 Hz) and wavelengths less than 10 ...
The demon core (like the core used in the bombing of Nagasaki) was, when assembled, a solid 6.2-kilogram (14 lb) sphere measuring 8.9 centimeters (3.5 in) in diameter.. It consisted of three parts made of plutonium-gallium: two hemispheres and an anti-jet ring, designed to keep neutron flux from "jetting" out of the joined surface between the hemispheres during implosi
The typical gamma rays given off by the weapon have an energy of about 2 MeV (mega electron-volts). The gamma rays transfer about half of their energy to the ejected free electrons, giving an energy of about 1 MeV. [24] In a vacuum and absent a magnetic field, the electrons would travel with a current density of tens of amperes per square metre ...
Radiation damage is the effect of ionizing radiation on physical objects including non-living structural materials. It can be either detrimental or beneficial for materials. Radiobiology is the study of the action of ionizing radiation on living things, including the health effects of radiation in humans.
