Long term risks of medical radiation often ignored
Doctors and patients should be more aware of the long term risks of radiological investigations such as x-rays and CT scans, argues a researcher in this week's BMJ. Use of radiation for medical examinations and tests is the largest manmade source of radiation exposure, yet doctors are insufficiently aware of the long term health risks associated... view more...

Radiologists, medical physicists work to make imaging procedures safer
The Radiological Society of North America (RSNA) reaffirmed its commitment to patient safety today in responding to a study and accompanying perspective on radiation dose from medical imaging procedures in the New England Journal of Medicine (NEJM). view more (2009-08-28)
Proton therapy lowers chance of later cancers
Patients who are treated with proton therapy (a specialized type of external beam radiation therapy using protons rather than X-rays to treat cancer) decreases the risk of patients developing a secondary cancer by two-fold, compared to being treated with standard photon radiation treatment. view more (2008-09-22)
Columbia researchers: Growth of CT scan use may lead to significant public health problem
Computed Tomography (CT) scans are an increasingly used X-ray-based tool for providing a three-dimensional view of a particular organ or tissue. view more (2007-11-29)
The National Radiological Protection Board advises holiday makers against overexposure to high sunlight
The incidence of skin cancer in the UK has significantly increased in recent years. There are now over 40,000 new cases and nearly 2,000 deaths from skin cancer in the UK each year. Much of this increase has been attributed to overexposure to sunlight not only when abroad but also sunbathing at home. In one recent study in Scotland, a third of... view more... (2003-05-27)
Study to assess the effects of mobile phones on hearing nears end of first phase
Scientists at the Institute of Sound and Vibration Research (ISVR) at the University of Southampton are nearing the end of the first phase of a study to assess whether the use of mobile phones has any adverse effect on the hearing of healthy young adults. The study into Potential Adverse Effects of GSM Cellular Phones on Hearing (known by the... view more... (2003-09-25)
Melanoma risk only partially associated vith exposure to UVB from sunlight
Researchers at The University of Texas M. D. Anderson Cancer Center have found that the risk of developing melanoma, the most deadly form of skin cancer, is only partially associated with exposure to ultraviolet B (UVB) radiation, the rays in sunlight that increase in summer and cause sunburn. view more (2005-12-21)
New radiation technique can greatly reduce painful skin burns in women with breast cancer
Breast cancer patients who undergo a new radiation technique called intensity modulated radiation therapy (IMRT) after surgery are three times less likely to have severe skin reactions from the treatment compared to standard radiation therapy. view more (2006-11-07)
Antioxidants could provide all-purpose radiation protection
Two common dietary molecules found in legumes and bran could protect DNA from the harmful effects of radiation, researchers from the University of Maryland report. Inositol and inositol hexaphosphate (IP6) protected both human skin cells and a skin cancer-prone mouse from exposure to ultraviolet B (UVB) radiation, the damaging radiation found in... view more...

Broccoli sprout-derived extract protects against ultraviolet radiation
A team of Johns Hopkins scientists reports in this week's issue of the Proceedings of the National Academy of Sciences that humans can be protected against the damaging effects of ultraviolet (UV) radiation - the most abundant cancer-causing agent in our environment - by topical application of an extract of broccoli sprouts. view more (2007-10-23)
CT scans: Too much of a good thing can be risky
Patients who undergo numerous CT scans over their lifetime may be at increased risk for cancer, according to a study published in the April issue of Radiology. view more (2009-03-31)
More sun exposure may be good for some people
A new study by scientists at the U.S. Department of Energy's Brookhaven National Laboratory and colleagues in Norway suggests that the benefits of moderately increased exposure to sunlight - namely the production of vitamin D, which protects against the lethal effects of many forms of cancer and other diseases - may outweigh the risk of developing... view more...

Assessing health risks of exposure to radiation
More accurate estimates of doses and health risks associated with occupational exposure to radiation can now be made thanks to the work of the International Commission on Radiological Protection (ICRP). Speaking at the Society for Radiological Protection`s Internal Dosimetry conference at the British Library today (23 October 2002), John Stather,... view more... (2002-10-18)
Chest X-ray exposure may increase likelihood of breast cancer
An analysis of 1,600 women with BRCA 1/2 mutations suggests that exposure to chest X-rays may increase the risk of breast cancer, and that exposure before the age of 20 may be linked to particularly heightened risk. view more (2006-06-27)
Rare pancreatic cancer patients may live longer when treated with radiation therapy
Radiation therapy is effective in achieving local control and palliation in patients with pancreatic neuroendocrine tumors (PNTs), despite such tumors being commonly considered resistant to radiation therapy. view more (2009-11-23)
Sunscreens can damage skin, researchers find
Are sunscreens always beneficial, or can they be detrimental to users? A research team led by UC Riverside chemists reports that unless people out in the sun apply sunscreen often, the sunscreen itself can become harmful to the skin. view more (2006-08-29)
NRPB Advisory Group on Non-ionising Radiation - Power Frequency Electromagnetic Fields and the Risk of Cancer
NRPB Advisory Group on Non-ionising Radiation Power Frequency Electromagnetic Fields and the Risk of Cancer After a wide-ranging and thorough review of scientific research, an independent Advisory Group (Chairman: Sir Richard Doll) to the Board of NRPB has concluded that the power frequency electromagnetic fields that exist in the vast majority of... view more...

Timing of radiation treatments for colon cancer may need adjusting, Jefferson researchers say
Scientists have unexpectedly discovered that mice with the gene defect that causes colon cancer in humans can differ from normal mice in how they respond to radiation treatments. view more (2006-04-10)
Study tracks increasing use of CT on pregnant women
Researchers have found that over a 10-year period radiologic exams on pregnant women have more than doubled, according to a study published in the online edition of Radiology. view more (2009-03-17)
Childhood cancer survivors treated with radiation face increased risk of tumors later in life
University of Minnesota cancer researchers found that children who received radiation treatment for cancer face an increased risk for brain and spinal column tumors later in life. view more (2006-11-02)
