2-drug combination may alleviate radiation sickness in people A combination of two drugs may alleviate radiation sickness in people who have been exposed to high levels of radiation, even when the therapy is given a day after the exposure occurred, according to a study led by scientists from Dana-Farber Cancer Institute and Children's Hospital Boston. Mouse studies of other potential therapies suggest they would be effective in humans only if administered within a few minutes or hours...
Researchers have released a preliminary report on the effects of the Fukushima nuclear disaster on the surrounding areas, following radiation levels for approximately three months following the event and surveying more than 5,000 people in the region. The report was published in the Nov. 16 issue of the online journal PLoS ONE. The researchers, led by Ikuo Kashiwakura of Hirosaki University in Japan, found only 10 people with high radiation exposure levels within 1 month after the...
By combining three layers of detection into one new device, a team of researchers from Japan has proposed a new way to monitor radiation levels at power plant accident sites. The device would be more economical that using different devices to measure different types of radiation, and could limit the exposure times of clean-up workers by taking three measurements simultaneously. Radioactive decay produces three flavors of emissions: alpha, beta, and gamma. Alpha particles comprise 2...
NEW YORK, Oct. 31, 2011 /PRNewswire/ -- Althera Medical Ltd. announced today that it intends to perform a First-in-Human study for its revolutionary treatment of cancer tumors with alpha radiation at Israel's eminent Rabin Medical Institute. Professors Benjamin Corn, M.D., Chairman of Radiation Oncology at the Sourasky Medical Center and Althera's Chief Medical Officer, and Aron Popovtzer, M.D., Chief of the Head and Neck Tumor Service at Rabin's Beilinson Hospital will lead the study....
Researchers from Massachusetts General Hospital, Harvard Medical School and CIC bioGUNE discover a complex cell mechanism activated by a protein —HOXB9— that becomes an obstacle for radiation effectiveness. Scientists all over the world continue to focus their research on breast cancer. As a consequence, knowledge of the behavior of tumor cells is growing, as well as of their interactions with the microenvironment. There are, however, many questions still unanswered. A new...
High-definition CT scans reduce radiation exposure Canadian Journal of Cardiology (www.onlinecjc.ca) has published a paper on the safety of cardiac imaging methods. This study is important for patients worried about radiation exposure during X-ray based studies of the heart. X-ray based methods have greatly improved the diagnosis of heart disease, but they can produce significant levels of radiation exposure. New imaging methods offer the possibility of much safer external...
Multiple radioactive "hot spots" in and around Tokyo -- some 125 miles from a nuclear facility damaged by a March earthquake -- have been detected by citizens using radiation-detection gear, various media outlets reported late last week. According to Chico Harlan of the Washington Post, residents reported on Thursday that they had discovered two areas with elevated radiation levels, some of which were higher than those within the 12-mile evacuation zone. One of those two readings could...
Actinium Pharmaceuticals, Inc., a leader in the field of cancer alpha radioimmunotherapy, successfully completed a first closing of $4.1 million in its Series E Financing, for which Laidlaw & Company (UK) Ltd. is exclusive placement agent. Newark, NJ (PRWEB) October 12, 2011 Actinium Pharmaceuticals, Inc., a leader in the field of alpha radioimmunotherapy for treatment of advanced cancers, is pleased to announce that it has successfully completed a first closing of $4.1 million in its...
News About Planet-Threatening Events Space is a violent place. If a star explodes or black holes collide anywhere in our part of the Milky Way, they’d give off colossal blasts of lethal gamma-rays, X-rays and cosmic rays and it’s perfectly reasonable to expect Earth to be bathed in them. A new study of such events has yielded some new information about the potential effects of what are called “short-hard” interstellar radiation events. Several studies in the past have...
LITTLETON, Mass., Oct. 3, 2011 /PRNewswire/ -- Mevion Medical Systems, Inc. announced today that it changed its name from Still River Systems, Inc. This change reflects the company's transition from a research and development organization to the commercial manufacturer of the MEVION S250(TM) Proton Therapy System. Proton therapy is widely regarded as the optimal means of delivering therapeutic radiation to treat a variety of cancers, but is not widely available because of the immense size,...

Nuclear fallout, or just simply fallout, known also as Black Rain, is the residual radioactive material that is propelled into the upper atmosphere after a nuclear black or a nuclear reaction that is conducted in an unshielded facility. It is so called because it "fall out" of the sky after the explosion and the shock wave have passed. It most commonly refers to the radioactive dust and ash that is created when a nuclear weapon explodes, but such dust can also come from a damaged nuclear...
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...
