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.

The growth of technology is such that it is not possible today for a nuclear physicist to switch into medical physics without training. The field is now much more technical. More training is needed to do the job.

I have the satisfaction of knowing I did something useful for society.

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.

When I entered the field in July 1958 I believed what they told me about radiation risks. I spent much effort reducing the dose to patients in radiology.

Medical physicists work in cooperation with doctors. A few medical physicists devote their time to research and teaching. A few get involved with administrative duties.

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

I was the Chair of the first department of medical physics in a medical school in the U.S.

There are now over 5,000 medical physicists in the U.S more than 50 times the number in 1958.

Many Nobel Prizes are awaiting good research to understand and explain the many mysteries of our bodies, such as the basic mechanism of memory or imagination.

In 1970 I realized that there was negligible risk from x-rays but many radiographs had poor image quality so that the risk from a false negative was significant.

I would not encourage everyone to take up this profession. Not everyone is suited for any particular field.

We developed simple test tools to optimize imaging parameters. No company was interested in our idea.

If someone is interested in medicine and also in physics and they like working with people and communicate well with others, I would strongly encourage them.

I have devoted much time and energy to helping medical physics in developing countries.

I am sure that I have been much more useful to society as a medical physicist.

In some cases radiation reduces the incidence of cancer.

I am not unhappy that my contribution was not recognized. I am sure it helped my career.

I don't display my plaques and honors. They are hidden behind a black curtain in my work room at home.

Nuclear physics is interesting but it is unlikely to help society.

Medical physics is an applied area of physics.

I found collaborating with congenial doctors about problems that physicists could help solve was very satisfying. I also like educating anybody who would listen!

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

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

I started the nuclear medicine laboratory at UW Hospitals in 1959 and trained radiology residents in the field. It was 1965 before they found a trained MD (doctor) to take over my role.

When I entered medical physics in 1958 there were fewer than 100 in the U.S. and I could see many opportunities to apply my knowledge of nuclear physics.

Roosevelt's magic lay in one facet of his personality: He knew how to take the risk. No other man in public life I knew could so readily take the challenge of the new.

I do think that our freedoms are at risk.

Many a man is praised for his reserve and so-called shyness when he is simply too proud to risk making a fool of himself.

Living at risk is jumping off the cliff and building your wings on the way down.

But on the other hand, in the midst of the chaos, you find normal people. You find people who are willing to risk their lives to tell you what they saw, even though they have no dog in the fight.

I don't see the risk, I enjoy performing stunts, and I don't get scared.

Every time in this century we've lowered the tax rates across the board, on employment, on saving, investment and risk-taking in this economy, revenues went up, not down.

What you risk reveals what you value.

For me, the risks in terms of opening that brewpub were fairly high. I put my house up as collateral, I invested the liquid money I had and two years of my time to get it over, but that's really not much of a risk for what the potential reward was if it worked.

The refusal to rest content, the willingness to risk excess on behalf of one's obsessions, is what distinguishes artists from entertainers, and what makes some artists adventurers on behalf of us all.

Film is the most expensive, highest risk industry in the world.

You can't get there by bus, only by hard work and risk and by not quite knowing what you're doing. What you'll discover will be wonderful. What you'll discover will be yourself.

You don't concentrate on risks. You concentrate on results. No risk is too great to prevent the necessary job from getting done.

Every day, hundreds of thousands of men and women protect and serve, often putting their own lives at risk.

When you remove the risk, you remove the challenge. When you remove the challenge, you wither on the vine.

I'm fighting for small businesses. I'm not fighting for big oil. Don't be confused. And there are thousands of businesses in this state that are at great risk. Meanwhile, the country keeps guzzling the oil, but we're out of work down here. We need to get back to work to build this region, and we intend to do so.

Nothing in life and nothing that we do is risk-free.

I feel that David took a risk with me. I have a sense that by starting off in the theatre and going off to do films you are seen to sell out in some way. I don't hold truck with that, but you can't stop people from feeling it.

You must accept that you might fail; then, if you do your best and still don't win, at least you can be satisfied that you've tried. If you don't accept failure as a possibility, you don't set high goals, you don't branch out, you don't try - you don't take the risk.

Kennedy did not have to run the risk of having his ideas and his words shortened and adulterated by a correspondent. This was the television era, not only in campaigning, but in holding the presidency.

The risk of a terrorist victory is greater when in fighting terror, democracy betrays its own essence.

Facts are, insurance ratings are really dependent on the notion that some people are higher risk than others.
