An emitted gamma ray from any type of excited state may transfer its energy directly to any electrons, but most probably to one of the K shell electrons of the atom, causing it to be ejected from that atom, in a process generally termed the photoelectric effect (external gamma rays and ultraviolet rays may also cause this effect).
The Effect of Gamma Rays on Man-in-the-Moon Marigolds is a play written by Paul Zindel, a playwright and science teacher.Zindel received the 1971 Pulitzer Prize for Drama and a New York Drama Critics' Circle Award for the work.
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 roles.
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.
Gamma rays are high-energy electromagnetic radiation; the others are particles that move slower than light. The neutrons result almost exclusively from the fission and fusion reactions, while the initial gamma radiation includes that arising from these reactions as well as that resulting from the decay of short-lived fission products.
Extreme ultraviolet and higher frequencies, such as X-rays or gamma rays are ionizing, and these pose their own special hazards: see radiation poisoning. The field strength of electromagnetic radiation is measured in volts per meter (V/m). [2]
[94] [95] The jets of gamma-ray bursts are ultrarelativistic, and are the most relativistic jets in the universe. [96] [97] The matter in gamma-ray burst jets may also become superluminal, or faster than the speed of light in the jet medium, with there also being effects of time reversibility.
Gamma rays are better absorbed by materials with high atomic numbers and high density, although neither effect is important compared to the total mass per area in the path of the gamma ray. Ultraviolet (UV) radiation is ionizing in its shortest wavelengths but is not penetrating, so it can be shielded by thin opaque layers such as sunscreen ...
