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.

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.

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.

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.

Socialism proposes no adequate substitute for the motive of enlightened selfishness that today is at the basis of all human labor and effort, enterprise and new activity.

Every American deserves to live in freedom, to have his or her privacy respected and a chance to go as far as their ability and effort will take them - regardless of race, gender, ethnicity or economic circumstances.

Achievement is not always success, while reputed failure often is. It is honest endeavor, persistent effort to do the best possible under any and all circumstances.

You really should not do this job unless you're willing to put in that enormous amount of effort. You should not do the job unless you're willing to take risks. And you shouldn't do the job unless you're willing to lose the job, too.

When families observe a later, deeper stage of cult involvement they may find it necessary to consider the involvement of a professional such as myself in an intervention effort.

Much effort, much prosperity.

No one will deny that the excessive use of alcohol and alcoholic beverages would do more than any other single factor to make impossible a total war effort.

Success requires first expending ten units of effort to produce one unit of results. Your momentum will then produce ten units of results with each unit of effort.

I'm not the type of person who goes through all this effort for a movie, and then doesn't care if anybody sees it. I want them to see it, and I want them to see it on the big screen.

It wasn't my plan to create such a record. All I did was put in the effort to win every match I played and it went on for weeks, months and years until my defeat to Ross Norman in Toulouse in 1986.

Periods of wholesome laziness, after days of energetic effort, will wonderfully tone up the mind and body.

Productivity is never an accident. It is always the result of a commitment to excellence, intelligent planning, and focused effort.

A minute of perfection was worth the effort. A moment was the most you could ever expect from perfection.

I'm always making a conscious effort to be viable and accessible.

A strenuous effort must be made to train young people to think for themselves and take independent charge of their lives.

If those committed to the quest fail, they will be forgiven. When lost, they will find another way. The moral imperative of humanism is the endeavor alone, whether successful or not, provided the effort is honorable and failure memorable.

Doyle stokes in a thousand shrewd touches with no effort at all. Wonderful.

I know, to banish anger altogether from one's breast is a difficult task. It cannot be achieved through pure personal effort. It can be done only by God's grace.

Sport is the habitual and voluntary cultivation of intensive physical effort.

The Russians obtained a number of plants under Lend-Lease, which had been authorized by Washington, that I thought were not justified for their war effort. They wanted them for postwar use.

I find it an effort to keep up appearances.

I am pleased to see that information campaigns, such as the America's WETLAND effort, are getting the message out, and people are beginning to realize that wetlands loss in Louisiana affects us all.
