Popularity: 6 Vote:	However, one of my ambitions in 1958 when I entered the field was to establish a department of medical physics in our medical school.
Popularity: 6 Vote:	I am not unhappy that my contribution was not recognized. I am sure it helped my career.
Popularity: 4 Vote:	I am now almost certain that we need more radiation for better health.
Popularity: 6 Vote:	I am sure that I have been much more useful to society as a medical physicist.
Popularity: 4 Vote:	I don't display my plaques and honors. They are hidden behind a black curtain in my work room at home.
Popularity: 8 Vote:	I found collaborating with congenial doctors about problems that physicists could help solve was very satisfying. I also like educating anybody who would listen!
Popularity: 8 Vote:	I found I liked practical applications of physics that are of benefit to society rather than basic research in nuclear physics.
Popularity: 5 Vote:	I have devoted much time and energy to helping medical physics in developing countries.
Popularity: 6 Vote:	I have long been convinced that medical physicists (and biomedical engineers) have useful roles to play in many clinical and basic science departments of medical schools.
Popularity: 3 Vote:	I have the satisfaction of knowing I did something useful for society.
Popularity: 8 Vote:	I invented bone densitometry in the early 1960s. It was of little interest at first because there was no known treatment.
Popularity: 5 Vote:	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.
Popularity: 9 Vote:	I still hope to find a biological scientist to test some of the basic ideas of my model of imagination and creativity.
Popularity: 8 Vote:	I was the Chair of the first department of medical physics in a medical school in the U.S.
Popularity: 2 Vote:	I would gladly trade any honorary award for the chance to give a lecture to the ACR or RSNA.
Popularity: 11 Vote:	I would not encourage everyone to take up this profession. Not everyone is suited for any particular field.
Popularity: 13 Vote:	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.
Popularity: 4 Vote:	In 1959 I learned from Dr Lester Paul, Chair of Radiology at UW that there was no method to detect early osteoporosis.
Popularity: 8 Vote:	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.
Popularity: 7 Vote:	In 1974 I started the nonprofit Radiation Measurements Inc (RMI) to manufacture and sell these QC test tools.
Popularity: 3 Vote:	In addition to bone densitometry I greatly enjoyed making thermoluminescent dosimetry (TLD) a useful technique. I didn't invent TLD but together with my graduate students we made it a useful technique.
Popularity: 7 Vote:	In some cases radiation reduces the incidence of cancer.
Popularity: 3 Vote:	It is likely that we need more radiation to improve our longevity.
Popularity: 5 Vote:	Many large hospitals have physics departments to do hospital work but not for training or research in medical physics.
Popularity: 5 Vote:	Many medical physicists take responsibility for radiation safety in their hospital.
Popularity: 3 Vote:	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.
Popularity: 7 Vote:	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.
Popularity: 7 Vote:	Medical physics is an applied area of physics.
Popularity: 7 Vote:	Moderate radiation to British radiologists (1955-1979) greatly reduced their death rates from non-cancer and improved their longevity by about three years - that is the increase in longevity that would occur if no one died from cancer!
Popularity: 3 Vote:	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.
Popularity: 2 Vote:	My main frustration is the fear of cancer from low dose radiation, even by radiologists.
Popularity: 3 Vote:	Nuclear physics is interesting but it is unlikely to help society.
Popularity: 10 Vote:	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.
Popularity: 2 Vote:	The profits and my salary from RMI were donated to the University to support medical physics research.
Popularity: 8 Vote:	There are now over 5,000 medical physicists in the U.S more than 50 times the number in 1958.
Popularity: 4 Vote:	There are now over 50,000 bone densitometers in the world. I doubt if more than 50 radiologists in the world know who invented the instrument. I have received little recognition for this contribution.
Popularity: 4 Vote:	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.
Popularity: 6 Vote:	We developed simple test tools to optimize imaging parameters. No company was interested in our idea.
Popularity: 8 Vote:	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.
Popularity: 4 Vote:	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.

Biography

John Cameron (1579 [?] - 1623) was a Scottish theologian.

Life and academic career

Cameron was born at Glasgow and received his early education in his native city. After having taught Greek in the university for twelve months, he removed to Bordeaux, where he was soon appointed a regent in the college of Bergerac. He did not remain long at Bordeaux, but accepted the offer of a chair of philosophy at Sedan, where he passed two years. He then returned to Bordeaux, and in the beginning of 1604 he was nominated one of the students of divinity who were maintained, at the expense of the church, and who for the period of four years were at liberty to prosecute their studies in any Protestant seminary. During this period he acted as tutor to the two sons of Calignon, chancellor of Navarre. They spent one year at Paris, and two at Geneva, whence they removed to Heidelberg. In this university, on April 4, 1608, he gave a public proof of his ability by maintaining a series of theses, De triplici Dei cum Homine Foedere, which were printed among his works. The same year he was recalled to Bordeaux, where he was appointed the colleague of Dr Primrose; and when Francis Gomarus was removed to Leiden, Cameron, in 1618, was appointed professor of divinity at Saumur, the principal seminary of the French Protestants.

In 1620 the progress of the civil troubles in France obliged Cameron to seek refuge for himself and family in England. For a short time he read private lectures on divinity in London; and in 1622 the king appointed him principal of the University of Glasgow in the room of Robert Boyd, who had been removed from his office in consequence of his adherence to Presbyterianism. Cameron was cordially disliked for his adherence to the doctrine of passive obedience. He resigned his office in less than a year.

He returned to France, and lived at Saumur. After an interval of a year he was appointed professor of divinity at Montauban. The country was still torn by civil and religious dissensions; and Cameron excited the indignation of the more strenuous adherents of his own party. He withdrew to the neighboring town of Moissac; but he soon returned to Montauban, and a few days afterwards he died at the age of about forty-six. Cameron left by his first wife several children, whose maintenance was undertaken by the Protestant churches in France. All his works were published after his death.
