Quotes About Radiation

Another consequence of an old expanding universe, besides its large size, is that it is cold, dark and lonely. When any ball of gas or radiation is expanded in volume, the temperature of its constituents falls off in proportion to the increase in its size. A universe that is big and old enough to contain the building blocks of complexity will be very cold and the levels of average radiant energy so low that space will everywhere appear dark.

Finally, consciousness itself may end or vanish in a humanity that has become completely etherealized, losing the close-knit organism, becoming masses of atoms in space communicating by radiation, and ultimately perhaps resolving itself entirely into light. That may be an end or a beginning, but from here it is out of sight.

The human breathes in radiation since that becomes a trend of self-harm, risking life in scientific artifacts.

The radiation left over from the Big Bang is the same as that in your microwave oven but very much less powerful. It would heat your pizza only to minus 271.3*C - not much good for defrosting the pizza, let alone cooking it.

I am now almost certain that we need more radiation for better health.

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.

People do really well on space missions, but it's the physiological, the medical stuff, the stuff like radiation, loss of bone mass and muscle mass and density. It's those things that we need to figure out.

Too many radiologists still believe there is a risk from a chest x-ray. Few radiologists can explain radiation to the patient in words the patient can understand.

My main frustration is the fear of cancer from low dose radiation, even by radiologists.

It is likely that we need more radiation to improve our longevity.

My discovery that black holes emit radiation raised serious problems of consistency with the rest of physics. I have now resolved these problems, but the answer turned out to be not what I expected.

I go for my completely routine mammogram and then I get a call from my gynecologist. And she says, 'Well, I have some - it's not such great news, but here it is, but it's very small and we're just going to get in there and take it right out, right away, and then you'll probably have radiation.'

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.

Normally, in the presence of radiation, communication links fail. But with autonomous robots, you don't need communications.

The radiation was worse by far. I had bandages all over my head. I looked like a mummy. On the side of my head and neck and down to my collarbone, I had second-degree burns. My skin blistered and peeled before it grew back. That was the worst part of it.

It seemed to me that NASA, especially Goddard, was the place where I could carry out the dreams that I had, which were to push forward an experiment that would measure the big bang radiation better than anyone had ever tried before. Therefore, it seemed like the perfect place to go.

Radiation is one of the important factors in evolution. It causes mutation, and some level of mutation is actually good for evolution.

The early universe was a dusty place, and the UV radiation from the hot, young black holes and stars would get enshrouded by dust, re-radiated, and scattered into red wavelengths like infra-red, causing these objects to remain obscured.

When you're asked to have a CT scan or a nuclear scan, do you know how much radiation that involves? How many of those sorts of scans have you already had? Is it necessary? Is there an alternative? I don't think many people know about that.

Black holes are pretty scary when you ponder them. They seem nihilistic, infinitely destructive on an inconceivable scale, notwithstanding the ideas of Hawking radiation.

My beloved husband goes through radiation, and a book of sonnets is my passionate response. And then after he dies, I write another book of poems as a farewell. The two keywords here are passion and joy. I simply have a passion for writing, and I do it with joy.

If you go on a journey to Mars and get into deep space, there is several hundred times, maybe 300 times the radiation.

A radiometer is a device for measuring the intensity of radiation. A microwave radiometer consists of a filter to select a desired band of frequencies followed by a detector which produces an output voltage proportional to its input power.

Mars does not have an atmosphere and does not have a magnetic field today, so the planet doesn't have the protection from radiation that our atmosphere and magnetic fields provide us on Earth.
