John Cameron Quotes
-
It is likely that we need more radiation to improve our longevity.
-
I was the Chair of the first department of medical physics in a medical school in the U.S.
-
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.
-
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.
-
I am now almost certain that we need more radiation for better health.
-
I have devoted much time and energy to helping medical physics in developing countries.
-
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 would not encourage everyone to take up this profession. Not everyone is suited for any particular field.
-
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.
-
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.
-
There are now over 5,000 medical physicists in the U.S more than 50 times the number in 1958.
-
I am sure that I have been much more useful to society as a medical physicist.
-
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.
-
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.
-
In some cases radiation reduces the incidence of cancer.
-
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.
-
I have the satisfaction of knowing I did something useful for society.
-
I am not unhappy that my contribution was not recognized. I am sure it helped my career.
-
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.
-
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.
-
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.
-
My main frustration is the fear of cancer from low dose radiation, even by radiologists.
