Radiation FAQs:

Q: Is radiation the emission or transmission of energy in the form of waves or particles through space or through a material medium?

A: Yes.

Q: Is radiation often categorized as either ionizing or non-ionizing depending on the energy of the radiated particles?

A: Yes.

Q: Is radiation used to determine the composition of materials in a process called neutron activation analysis?

A: Yes.

Q: Is radiation still not well understood and currently estimates are loosely determined by population based on data from the atomic bombing in Japan and from reactor accident follow-up?

A: Yes, such as with the Chernobyl disaster.

Q: Is radiation at maximum is given by Wien's displacement law and is a function of the body's absolute temperature?

A: Yes.

Q: Is radiation an idealized spectrum of radiation emitted by a body that is at a uniform temperature?

A: Yes.

Q: Is radiation subatomic particles accelerated to relativistic speeds by nuclear reactions?

A: Yes.

Q: Is radiation capable of causing thermal-ionization if it deposits enough heat to raise temperatures to ionization energies?

A: Yes.

Q: Was radiation discovered with the neutron by Chadwick?

A: Yes, and in 1932.

Q: Is radiation the emission of positrons?

A: Yes, and which are the antimatter form of electrons.

Q: Is radiation produced artificially in particle accelerators?

A: Yes, and through the last half of the twentieth century.

Q: Is radiation too small to produce charged ions when passing through matter?

A: Yes.

Q: Is radiation far less hazardous per unit of energy?

A: Yes.

Q: Is radiation a common synonym for infrared radiation emitted by objects at temperatures often encountered on Earth?

A: Yes.

Q: Are radiations only gradually understood in later years?

A: Yes.

Q: Is radiation generated when energy from the movement of charged particles within atoms is converted to electromagnetic radiation?

A: Yes.

Q: Is radiation invisible and not directly detectable by human senses?

A: Yes, as a result, instruments such as Geiger counters are usually required to detect its presence.

Q: Is radiation a radioactive material or a nuclear process such as fission or fusion?

A: Yes, and there is particle radiation to consider.

Q: Is radiation radioactive materials that emit α?

A: Yes, and β, or γ radiation, consisting of helium nuclei, electrons or positrons, and photons, respectively.

Q: Is radiation considered to increase the risk of cancer?

A: Yes.

Q: Is radiation dangerous when alpha-emitting radioisotopes are ingested or inhaled?

A: Yes, This brings the radioisotope close enough to sensitive live tissue for the alpha radiation to damage cells.

Q: Is radiation ascribed to William Herschel?

A: Yes, and the astronomer.
