A Quote by Ernest Rutherford
[From uranium] there are present at least two distinct types of radiation one that is very readily absorbed, which will be termed for convenience the ? radiation, and the other of a more penetrative character, which will be termed the ? radiation.

There are allowable limits for radiation going - I mean there's radiation all around us. There's radiation from your television set. There's radiation from your computer. There's radiation actually occurring in the ground.
My experiments proved that the radiation of uranium compounds can be measured with precision under determined conditions and that this radiation is an atomic property of the element of uranium.
Ionizing radiation may well be the most important single cause of cancer, birth defects, and genetic disorders... The stakes for human health are very, very high in radiation matters. It is essential that people take no chance that conflict-of-interest is producing radiation databases which...cannot be trusted.
There is no safe dose of radiation since radiation is cumulative. Harm in the form of excess human cancer occurs at all doses of ionizing radiation, down to the lowest conceivable dose and dose rate.
To the possible enquiry as to the probable character of a successful flying machine, the writer would answer that in his judgment two types of such machines may eventually be evolved: one, which may be termed the soaring type, and which will carry but a single operator, and another, likely to be developed somewhat later, which may be termed the journeying type, to carry several passengers, and to be provided with a motor.
When X-rays traverse matter of any kind, this matter becomes a source of a radiation similar in character to that of the primary radiation falling upon it.
Nuclear industry proponents often assert that low doses of radiation (eg below 100mSV) produce no ill effects and are therefore safe. But , as the US National Academy of Sciences BEIR VII report has concluded, no dose of radiation is safe, however small, including background radiation; exposure is cumulative and adds to an individual's risk of developing cancer.
Welcome to Perdido beach, where our motto is: Radiation, what radiation?
When all thermonuclear sources of energy are exhausted a sufficiently heavy star will collapse. Unless fission due to rotation, the radiation of mass, or the blowing off of mass by radiation, reduce the star's mass to the order of that of the sun, this contraction will continue indefinitely.
Not smoking enough will cause lung cancer! If anybody is getting a cancerous activity in the lung, the probabilities are that it's radiation dosage coupled with the fact that he smokes. And what it does is start to run out the radiation dosage, don't you see.
The universe will finally become a ball of radiation, becoming more and more rarified and passing into longer and longer wave-lengths. The longest waves of radiation are Hertzian waves of the kind used in broadcasting. About every 1500 million years this ball of radio waves will double in diameter; and it will go on expanding in geometrical progression for ever. Perhaps then I may describe the end of the physical world as-one stupendous broadcast.
Radiation doesn't recognize borders. A meltdown in Japan or India, say, is a danger to the whole world. Wind circulates the radiation everywhere. Water quality is affected. We all eat the same fish. We use products from all over the world - if something is contaminated, it will cause harm.
It's true that non-ionizing radiation lacks the power to have damage. But its damage seems to come from its modulated signal. So every 900 milliseconds, if you have a cellphone in your pocket, it's getting half of that radiation which is getting into you as it seeks the signal from the tower.
Since we can produce all types of light by means of hot bodies, we can ascribe, to the radiation in thermal equilibrium with hot bodies, the temperature of these bodies, and thus every radiation, even that issuing from a phosphorescent body, has a certain temperature for every colour.
The Atomic Age was born in secrecy, and for two decades after Hiroshima, the high priests of the cult of the atom concealed vital information about the risks to human health posed by radiation. Dr. Alice Stewart, an audacious and insightful medical researcher, was one of the first experts to alert the world to the dangers of low-level radiation.
The worst situation with radiation escaping is if you are downwind from it. You could virtually be on one side and not affected by the radiation. If you're on the other side and you're downwind from it, you are going to be affected.
