After eight years of fighting, and multiple rounds of chemotherapy, surgery, and radiation, my mother lost her battle with cancer. I think about her every day. I miss her terribly, and wish she were there to walk me down the aisle at my wedding and to cheer when my sister received her college diploma.

One of the major problems with long-term deep space human flight is the requirement for radiation shielding.

A radio telescope pointing at the sky receives radiation not only from space, but also from other sources including the ground, the earth's atmosphere, and the components of the radio telescope itself.

It's very dangerous to put astronauts on a moon base where there's radiation, solar flares and micro meteorites. It'd be much better to put robots on the moon and have them mentally connected to astronauts on the Earth.

In the Radiation Laboratory we count it a privilege to do everything we can to assist our medical colleagues in the application of these new tools to the problems of human suffering.

The technology used to detect if vehicles are carrying radioactive material is so sensitive it can tell if a person recently received radiation as part of a medical procedure.

Nobody could tell us or really had a very good idea, if there were a massive release of radiation, what kind of medical treatment people were going to need and this or that, or, indeed, whether there would be medical personnel around.

Most medical physicists work in the physics of radiation oncology making sure that the desired dose is given to the cancer and the dose to normal tissues are minimized.

Using predictive models from engineering and public health, designers will plan safer, healthier cities that could allow us to survive natural disasters, pandemics, and even a radiation calamity that drives us underground.

I do comparative studies of climate evolution, and the interactions between planetary atmosphere and surfaces and their radiation environment, and try to understand the environmental factors that can affect a planet's habitability and how they change over time.

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

"In a cocoon of individualism. In an authentic bunker of skepticism, nihilism, apolitical non-conformism. Protecting himself from the radiation of mass hysteria and the herd instinct of the matrix system.

There would be no more offerings. Not this day. Not any day. Humankind had suffered enough for its love of Gods, its long search for God. He thought of the many centuries in which his people, the Jews, had negotiated with God, complaining, bickering, decrying the unfairness of things but always - always - returning to obedience at whatever the cost. Generations dying in the ovens of hatred. Future generations scarred by the cold fires of radiation and renewed hatred.

I will continue to push for doubling the strength of the U.S. Border Patrol and to make sure that every cargo container that enters this nation is screened for radiation and potential weapons of mass destruction.

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

I am a type-2 diabetic and they took me off medication simply because I ate right and exercised. Diabetes is not like a cancer where you go in for chemo and radiation. You can change a lot through a basic changing of habits.

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.
