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

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.

Yeah, that's what kind of, we get the idea a little bit yeah, because other people from different countries also try as hard as they can to get a medal or a gold medal in the Olympic Games. And you know, if they can work hard, we can work hard as well.

If we wait for the U.S. to do something, we will be waiting for a very long time. It's Europe, it's Australia, it's the other developed and middle developing countries that have got to do the job.

These interests of the workers, as the exploited and oppressed, class of society, are the same in all countries.

Countries under foreign command quickly forget their history, their past, their tradition, their national symbols, their way of living, often their own literary language.

I have to say that it's very few countries that are willing to look back at its past and apologize for its act, or make amends for its act, as the United States had one.

Grossing Out dealt with the western nations selling arms to the Third World and exploiting these countries.

One of the biggest development issues in the world is the education of girls. In the United States and Europe, it has been accepted, but not in Africa and the developing countries.

It is normal for politicians in all countries to profess themselves the pupils of history, anxious to draw the right lessons from her teaching.

After the 1954 Geneva international conference, Vietnam was divided into two parts. On paper, North and South Vietnam were twin countries born at the same moment.

Most of the international community, most of the countries around the world, don't want any side, any party to take unilateral steps. They would like that all of us to stick to the road map.

We are at war to liberate Iraq, to protect the people of the United States and other countries from the devastating impact of Iraqi weapons of mass destruction being used by terrorists or the Iraqi government to kill thousands of innocent civilians.

Nor is the suffering limited to children in developing countries.

If some countries have too much history, we have too much geography.

The Baltic Sea is becoming more and more polluted. Not everybody living near the shore of the Baltic Sea is protecting it. It is the water of life for countries like Finland and Sweden.

The U.S. routinely ranks lower than other countries in health outcomes such as infant mortality.

The unthinkable occurred: two communist countries went to war with each other.

Unless we repeal the illegal Byrd amendment, American exports will be vulnerable to retaliation, and the U.S. will continue to face a difficult task convincing other countries to make their laws comply with international rules.

Well, by the standards of a lot of countries, by Latin American standards, it wasn't so bad.

For, behind the scenes, halfway around the world in Mexico, were two decades of aggressive research on wheat that not only enabled Mexico to become self-sufficient with respect to wheat production but also paved the way to rapid increase in its production in other countries.

Let us work toward greater cooperation with all Caribbean Countries, whether we speak English, Dutch, French or Spanish, whether we are independent or not, and whether we be island or continental territories.

For the first time in history all the major countries in the world are pushing together to reach this goal... building something in space that is really for all humankind.

It seems proper, at all events, that by an early enactment similar to that of other countries the application of public money by an officer of Government to private uses should be made a felony and visited with severe and ignominious punishment.
