Low dose radiation in infancy may affect intellect
Exposure to low doses of ionising radiation in infancy affects intellectual capacity in later life, conclude researchers from Sweden in this week's BMJ. CT scanning, which delivers high doses of ionising radiation, is increasingly being used in young children after minor head trauma. The study... view more (2004-01-03)

New technique reduces radiation exposure by 60 percent in abdominal CT of children
By lowering the tube current to account for both the weight and body symmetry of a child, an abdominal CT radiation dose can be reduced by 60% without compromising the image quality.   view more (2006-05-02)

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)

REDUCED LONGEVITY OF ATOMIC-BOMB SURVIVORS (p 303)
A study in this week's issue of THE LANCET does not support claims that atomic-bomb survivors exposed to certain doses of radiation live longer than comparable unexposed individuals. There have been conflicting claims regarding the biological and health consequences of exposure to low doses of... view more (2000-07-19)

New study focuses on radiation-associated cancer risks
Concerns about the risk of radiation-induced cancer are growing with the increasing number of cancer patients surviving long term.   view more (2007-01-12)

Livermore researchers find
With the exception of lasers and free-electron lasers, there hasn't been another fundamental way to produce coherent light for close to 50 years.   view more (2006-01-16)

Optimal adjuvant radiation therapy associated with improved survival, meta-analysis shows
A new analysis of adjuvant radiation therapy in women with breast cancer following mastectomy is associated with better survival as measured at 10 years when appropriate doses and fields of radiation are used.   view more (2006-01-04)

Radiation after surgery doubles survival time for some lung cancer patients
Patients with lung cancer that has spread to mediastinal lymph nodes - located between the chest, breastbone and spine - who receive radiation after surgery and chemotherapy live twice as long as patients who do not receive radiation after surgery.   view more (2006-11-07)

New radiation protection technique results in reduced physician exposure
A new radiation protection technique can significantly reduce physician radiation exposure during coronary angiography, according to a researcher at the University of Maryland Medical Center in Baltimore, MD.   view more (2006-05-03)

Men with prostate cancer avoid radiation due to misconceptions
Negative perceptions about radiation therapy can strongly influence a prostate cancer patient's choice to avoid external beam radiation therapy, even though studies have proven the treatment to be as safe and effective as other treatments for the disease, including surgery.   view more (2006-11-06)

Combination therapy shows improvement for breast cancer patients
Giving radiation therapy and chemotherapy at the same time after a lumpectomy helps keep breast cancer from returning locally.   view more (2006-12-01)

Tackling the threat of nuclear terrorism
The only effective way to tackle the threat of nuclear terrorism is to abolish nuclear weapons and establish strict international control of all fissile materials that could be used to make new weapons, argue three US physicians in this week's BMJ. In the aftermath of 11 September 2001, nuclear... view more (2002-02-06)

Combination therapy reduces tumor resistance to radiation
Radiation is used to treat a variety of tumors and the response of tumors to radiation is dependent on endothelial cell death, which in turn limits oxygen delivery to the tumor, causing hypoxia and tumor cell death.   view more (2007-06-08)

Largest PSA bounce study eases worry of prostate cancer returning
Prostate cancer patients who have a temporary rise in their prostate specific antigen (PSA) levels after radiation therapy-called a PSA bounce-are not at an increased risk of their cancer coming back any more than those who don't have a temporary rise.   view more (2006-11-09)

Cancer Gene Radiation Therapy Discovery
Dr Tracy Robson, a lecturer in molecular radiation science at the University's Jordanstown campus, has isolated a novel gene, called DIR-1, which can alter a tumour cell's susceptibility to radiation therapy.   view more (1999-09-20)

A new project to test a pioneering method to advance technology
Technological advances take place all the time – driven by need. But can these advances be speeded up in quantum leaps? The European Space Agency thinks they can, and is launching a pioneering project to test this.   view more (2002-03-27)

Towards predicting late-stage radiation toxicity
Radiation is a brutal and in many cases necessary part of cancer therapy. More 50% of cancer patients receive radiotherapy as part of their treatment, and many experience concurrent negative side effects.   view more (2006-10-31)

University Scientists Will Not See the Eclipse...At Least, Not With Their Eyes!
The sun constantly radiates energy across the spectrum of frequencies from radio, through heat, to visible light and beyond. During the period of totality, only radiation present in the sun's annular corona will be detectable, with energy directly radiated from the sun being masked by the moon.   view more (1999-08-06)

Patients regain cognitive function after radiation for brain tumors
Patients who suffer from low-grade brain tumors are able to regain normal cognitive function after receiving radiation therapy to shrink their tumor.   view more (2005-11-16)

Order of chemotherapy, radiation has no effect on breast cancer survival
For women who have had surgery for early breast cancer, it may not matter whether they receive follow-up chemotherapy before, after or during radiation therapy, according to a new review of studies.   view more (2006-10-31)

Radiation dose reduction in liver cancer
A new digital angiography flat panel system reduces the radiation dose to patients undergoing interventional treatment for liver cancer by about one-fourth, a new study shows.   view more (2005-10-03)

Modern radiation therapy ups lung cancer survival
Modern three-dimensional radiation therapy has been proven to be more successful at curing lung cancer than older two-dimensional radiation therapy for some patients with early stage lung cancer.   view more (2006-09-01)

Jefferson researchers show chemotherapy and radiation together extend lung cancer patients' lives
Chemotherapy given at the same time as radiation therapy can help patients with a certain type of lung cancer live nearly 50 percent longer than they might have otherwise if the same treatment was given differently, according to an international team's analysis of several trial results.   view more (2007-11-12)

Combining PET and CT scans makes cancer treatment more accurate
Doctors have discovered that combining images derived from positron emission tomography and computed tomography in the planning and delivery of radiation treatment for patients with head and neck cancer leads to more accurate delivery of the radiation dose and an increased chance for survival.   view more (2006-05-02)

Precision radiation therapy yields rare success for liver tumors
Shaped-beam radiation therapy is a promising treatment for life-threatening metastatic liver tumors, according to researchers at the University of Rochester Medical Center who report an 88 percent success rate for controlling the lesions.   view more (2005-10-20)
