NEWPORT NEWS, Va., May 13, 2011 /PRNewswire/ -- The possibility of low-dose Molecular Breast Imaging (MBI) looks promising according to the most recent clinical evidence revealed this past month at the National Institutes of Health (NIH). Dr. Marcela Bohm-Velez and her colleagues from Associates in Pittsburgh, Pa., shared preliminary results from a prospective study on low-dose MBI, specifically Breast-Specific Gamma Imaging (BSGI), at the SNM Breast Cancer Imaging: State of the Art 2011....

In the midst of ongoing concerns about radiation exposure from the Fukushima nuclear power plant in Japan, scientists are reporting that a substance similar to resveratrol "” an antioxidant found in red wine, grapes and nuts "” could protect against radiation sickness. The report appears in ACS Medicinal Chemistry Letters.Michael Epperly, Kazunori Koide and colleagues explain that radiation exposure, either from accidents (like recent events in Japan) or from radiation therapy for cancer,...

The use of breast shields is the technique of choice to protect the breasts of women from radiation exposure while undergoing chest CT examinations, according to a new study.The use of CT has grown exponentially which brings into question the level of radiation exposure to patients. Recently the International Commission of Radiation Protection (ICRP) increased the tissue weighting factor for the breast from 0.05 to 0.1 noting that breast tissue is even more sensitive to radiation exposure...

MESSENGER carries a Gamma-Ray Spectrometer (GRS) that is capable of measuring and characterizing gamma-ray emissions from the surface of Mercury. Just like radio waves, visible light, and X-rays, gamma rays are a form of electromagnetic radiation, but with higher energies than those other types of radiation. Gamma rays coming from Mercury carry information about the concentrations of elements present on its surface, so observations from the MESSENGER GRS are being used to determine the...

SHELTON, Connecticut, May 4, 2011 /PRNewswire/ -- Women in the U.S. will now have the same opportunity as millions of European women already have­; to undergo mammography with a significantly lower radiation dose. This is the result of the U.S. Food and Drug Administration's (FDA) clearance of the Swedish IT and medical technology company Sectra's digital mammography system, Sectra MicroDose Mammography(TM) (http://www.sectra.com/pr-microdose). Achieving best-in-class cancer...

Proton radiography imaging used prior to and during proton treatments for pediatric cancer patients provides for more accurate treatment delivery and a lower dose of radiation compared to standard diagnostic X-rays and cone beam CT, according to a study presented today at the Cancer Imaging and Radiation Therapy Symposium in Atlanta. The symposium is co-sponsored by the American Society for Radiation Oncology (ASTRO) and the Radiological Society of North America (RSNA).The amount of radiation...

On April 26, 1986, history's greatest nuclear accident took place northwest of the Ukrainian city of Chernobyl. Despite the scale of the disaster, 25 years later, we still do not know it's real effects. An international team of investigators has shown for the first time that the color of birds' plumage may make them more vulnerable to radioactivity.Radiation causes oxidative stress, damages biological molecules and may have "important" negative effects on organisms in relatively...

HAMPTON, Va., April 26, 2011 /PRNewswire-USNewswire/ -- Flying somewhere and want to find out your exposure to galactic and solar radiation? A new update to an iPhone app will let you do that. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The $1.99 "SpaceWx" app provides real-time information about exposure to radiation from solar activity and other sources from space, starting at an altitude of 16,000 feet (5 kilometers). Exposure levels are broken down by altitude and...

(Ivanhoe Newswire) -- It has been 25 years since the Chernobyl nuclear disaster. Now, researchers say investigating that incident may help us better understand health consequences of nuclear accidents in the past, present, and future.Radioactive elements with a long half-life (the time it takes for half the sample to decay), especially caesium and strontium, will be prevalent in the environment for decades to come. Radioactive iodine, despite having a half-life of just eight days, can cause...

Incoming Solar Radiation Impacts By Various Weather Cycles
2012-08-22 13:30:39

The above image looks at the month of March for the three cycles known as Normal Phase, El-Nino, and La-Nina. The data was recorded for the city of Honolulu Hawaii, during the month of March. Remember this is just data for one month during these cycles. Normal: During this cycle incoming solar activity was upwards to 48% efficient for the month, producing less than 50% of the month which is due to the large amount of daily cloud cover that is seen on the island during the early morning and...

The above image looks at the month of March for the three cycles known as Normal Phase, El-Nino, and La-Nina. The data was recorded for the city of Austin Texas. Remember this is just data for one month during these cycles. Normal: During this cycle incoming solar activity was upwards to 60% efficient for the month, producing enough solar energy that only 40% of the month would have not had strong incoming radiation. EL-Nino: This phase provided the area with an extended number of...

Electromagnetic Spectrum -- The electromagnetic spectrum describes the various types of electromagnetic radiation based on their wavelengths. Radio, representing wavelengths from a few feet to well over a mile, is at one end of the spectrum. Gamma ray radiation is at the other end: the wavelength of the harder types is so short, in the subatomic range, that we do not have instruments capable of directly measuring it. While the above classification scheme is generally accurate, in...

Electromagnetic Radiation -- Electromagnetic radiation is a combination of oscillating electric and magnetic fields propagating through space and carrying energy from one place to another. Light is a form of electromagnetic radiation. The theoretical study of electromagnetic radiation is called electrodynamics, a subfield of electromagnetism. When any wire (or other conducting object such as an antenna) conducts alternating current, electromagnetic radiation is propagated at the same...

Solar Radiation -- Solar radiation is radiant energy emitted by the sun due to nuclear fusion reactions. Fusion is the process whereby stars produce huge quantities of energy from the fusion of hydrogen or helium, in one of the most efficient processes of energy generation. The radiation referred to is usually electromagnetic energy, particularly infrared radiation, visible light, and ultraviolet. Some stars are known to emit radiation of other wavelengths. Solar neutrinos are a...
