Radiation Quotes
In America, we have always taken it as an article of faith that we 'battle' cancer; we attack it with knives, we poison it with chemotherapy or we blast it with radiation. If we are fortunate, we 'beat' the cancer. If not, we are posthumously praised for having 'succumbed after a long battle.'
Abraham Verghese
There's almost no food that isn't genetically modified. Genetic modification is the basis of all evolution. Things change because our planet is subjected to a lot of radiation, which causes DNA damage, which gets repaired, but results in mutations, which create a ready mixture of plants that people can choose from to improve agriculture.
Nina Fedoroff
In this derivation Bohr had relied on the old idea of classical radiation theory, that the frequencies of spectral lines should agree with the frequency of the electron's orbital motion, but he had assumed this only for the largest orbits, with large n. The light frequencies he calculated for transitions between lower states, such as n=2 → n=1, did not at all agree with the orbital frequency of the initial or final state. So Bohr's work represented another large step away from classical physics.

To understand this radiation [ cosmic microwave background ], it is easier to begin thinking about the radiation from a very hot gas like that inside a neon light. The same neon... is, at room temperature, utterly transparent... The character of matter in general changes abruptly when it gets heated above 3,000 degrees or so. Below this temperature, matter is electrically neutral... At high temperatures in a neon light, the electrically charged pieces of atoms become unstuck. Frequent and violent collisions break down neutral atoms into electrons and unbalanced nuclei. Matter in this state is called plasma, and it radiates much of its collision energy in the form of light. ...a gas of neutral atoms (like air) is virtually transparent. The free [charged] nuclei and electrons of plasma, by contrast, couple to light's electromagnetic fields and absorb it very efficiently. ...You ...see light only from the borderline layer of neon between opaque plasma and transparent neutral atoms.

One of my chief "crimes" then, was to have wanted Iran to move from the oil age into the atomic age before it was too late. Must I blush for that? The peaceful use of nuclear energy did not create problems for radiation and contamination for us since we have vast stretches of desert...
I was accused of having adopted the plans for nuclear power stations among others for reasons of "personal ambition". Was it not obvious that I would be dead before most of these plans had been carried out? Why speak of personal ambition then? It was rather a question of forseeing Iran's needs. My "personal" ambitions are known to all men of good faith - to preserve national unity, to make the Iranian people as happy as possible and to prepare a more peaceful future.
