Actinometry: measuring the intensity of electromagnetic radiation (especially of the sun`s rays).

Radioactive: exhibiting or caused by radioactivity.

Hideki Yukawa: Japanese mathematical physicist who proposed that nuclear forces are mediated by massive particles called mesons which are analogous to the photon in mediating electromagnetic forces (1907-1981).

Arthur Compton: United States physicist noted for research on x-rays and gamma rays and nuclear energy; his observation that X-rays behave like miniature bowling balls in their interactions with electrons provided evidence for the quantal nature of light (1892-1962).

Absorption Spectrum: the spectrum of electromagnetic radiation that has passed through a medium that absorbed radiation of certain wavelengths.

Action Spectrum: the efficiency with which electromagnetic radiation produces a photochemical reaction plotted as a function of the wavelength of the radiation.

Radiogram: a photographic image produced on a radiosensitive surface by radiation other than visible light (especially by X-rays or gamma rays).

Homochromatic: (of light or other electromagnetic radiation) having only one wavelength.

Actinic Radiation: electromagnetic radiation that can produce photochemical reactions.

Beam: a group of nearly parallel lines of electromagnetic radiation.

Transparence: permitting the free passage of electromagnetic radiation.

Light: (physics) electromagnetic radiation that can produce a visual sensation.

Actinometer: an instrument for measuring the intensity of electromagnetic radiation (usually by the photochemical effect).

Absorber: (physics) material in a nuclear reactor that absorbs radiation.

Absorbance: (physics) a measure of the extent to which a substance transmits light or other electromagnetic radiation.

Fallout: the radioactive particles that settle to the ground after a nuclear explosion.

Laser: an acronym for light amplification by stimulated emission of radiation; an optical device that produces an intense monochromatic beam of coherent light.

A: a metric unit of length equal to one ten billionth of a meter (or 0.0001 micron); used to specify wavelengths of electromagnetic radiation.

Radiation: energy that is radiated or transmitted in the form of rays or waves or particles.

Radiology: (radiology) examination of the inner structure of opaque objects using X rays or other penetrating radiation.

Radiant Energy: energy that is transmitted in the form of (electromagnetic) radiation; energy that exists in the absence of matter.

Absorptance: a measure of the rate of decrease in the intensity of electromagnetic radiation (as light) as it passes through a given substance; the fraction of incident radiant energy absorbed per unit mass or thickness of an absorber.

Radiology: the branch of medical science dealing with the medical use of X-rays or other penetrating radiation.

Radiation: syndrome resulting from exposure to ionizing radiation (e.g., exposure to radioactive chemicals or to nuclear explosions); low doses cause diarrhea and nausea and vomiting and sometimes loss of hair; greater exposure can cause sterility and cataracts and some forms of cancer and other diseases; severe exposure can cause death within hours.

High-Level Radioactive Waste: radioactive waste that left in a nuclear reactor after the nuclear fuel has been consumed.

Atomic Pile: a nuclear reactor that uses controlled nuclear fission to generate energy.

Atomic Number 92: a heavy toxic silvery-white radioactive metallic element; occurs in many isotopes; used for nuclear fuels and nuclear weapons.

A-Bomb: a nuclear weapon in which enormous energy is released by nuclear fission (splitting the nuclei of a heavy element like uranium 235 or plutonium 239).

Tributary: (of a stream) flowing into a larger stream.

Habitual Abortion: repeated spontaneous abortion (often for no known reason).

Blitheness: a feeling of spontaneous good spirits.
