    Despite the wide application of radiation in diagnostics and treatments, there is still no magic material to protect people from radiation exposure. Though Amifostine is developed as a radioprotectant, the FDA approved its application only for the protection of salivary glands. Also it requires repetitive injections to be effective and it can pose severe health threats of systemic toxicity and complications when applied to those under total body irradiation conditions. By growing manganese oxide (Mn3O4) nanocrystals on top of Cerium oxide (CeO2) nanocrystals, the research team boosted the catalytic activity of the CeO2/Mn3O4 nanocrystals in their ability to stave off...

    Using satellite data, researchers believe an "anomaly" in the South Atlantic may have split in two, with the eastern section "developing vigorously." Earth's magnetic field is generated by movements within the planet's molten iron core. ...When the magnetic field is stronger, it blocks more radiation. When it is weaker, more radiation reaches the planet's surface. The magnetic field is constantly moving. It strengthens and weakens as part of normal fluctuations. According to the European Space Agency, the magnetic field has lost around 9 percent of its strength over the preceding two centuries. One section of the magnetic field has been...

    Sure, the economy is causing a crisis, but what about anthrax? How about smallpox? In a little noticed move, federal officials this month have declared a series of public health emergencies relating to potential weapons of biological terror. On Oct. 1, Health and Human Services Secretary Mike Leavitt declared an anthrax public health emergency. On Oct. 10, he declared health emergencies for smallpox, radiation sickness from the detonation of a nuclear device and poisoning from botulinum toxins, the active ingredient of Botox. There’s no clear evidence that terrorists have managed to weaponize anthrax or stolen large caches of Botox from...

    First, let me say I am more than pleased in how my chemo and radiation treatments have been going. No nausea at all from the chemo and outside the pain from the arthritis in my shoulders holding my arms over my head for 15 to 20 minutes during radiation, I am not suffering much at all. Oh, I am down in the dumps at times and have fatigue to the max. I am sleeping about 16 hours a day. All in all, the whole experience has been much better than I ever expected and all thanks to you all who...

    The 2011 earthquake and tsunami that caused Fukushima's nuclear plant to melt down prompted the Japanese goverment to evacuate a huge area as dangerous radiation spread. The evacuated region, which was carved up into several zones based on how the radiation spread, has become home for a wide range of wild animals that apparently found a way to thrive amid the desolation despite the radiation. “Over time, some wildlife species have responded favorably to the absence of humans, even in the presence of high radiation levels, resulting in a rewilding of the evacuation zones,” Thomas Hinton, a radioecologist at the...

    Proton therapy leads to significantly lower risk of side effects severe enough to lead to unplanned hospitalizations for cancer patients when compared with traditional radiation, while cure rates between the two groups are almost identical. The findings come from an expanded analysis of the largest review of its kind, performed by researchers in the Perelman School of Medicine at the University of Pennsylvania, to evaluate whether or not patients undergoing radiation therapy at the same time as chemotherapy experienced serious adverse events within 90 days. Researchers found proton therapy reduces the relative risk of these side effects by two-thirds.

    Full Title: President Putin says five men killed in huge explosion in northern Russia that caused sudden radiation spike died trying to create a weapon that ‘has no equal in the world’ Russian President Vladimir Putin has told widows of the five scientists who died in a nuclear explosion earlier this year that their husbands were working on 'the most advanced and unmatched technical' weaponry. Putin's comments came during a ceremony of state decorations at the Kremlin today where he awarded the deceased employees of Russia's state nuclear company with the Order of Courage, posthumously.

    At age 35, with six months of chemotherapy and three weeks of radiation behind her for Hodgkin’s lymphoma, Oregon resident Karen Baas didn’t feel relief because her treatments had ended. She felt poisoned. “Of course I was grateful to have had treatment and get past it,” she told Runner’s World. “But before I got cancer, I was a vet tech, and one of the chemicals we use for euthanasia is red. It turned out one of my infusion chemo drugs is also red. I can’t tell you how disturbing it is to make that mental connection.” Three days after her...

    At the levels of radiation now being found a Fukushima, a robot would be able to operate for less than two hours before it was destroyed. And Japan’s National Institute of Radiological Sciences said medical professionals had never even thought about encountering this level of radiation in their work. The accident is enormous in its medical implications. Through future years, too long to contemplate, we will witness an epidemic of cancer as people inhale the radioactive elements, eat radioactive vegetables, rice and meat, and drink radioactive milk and teas. Year by year, decade through relentless decade, the radiation will build...
  • Russia’s Nuclear Monitors ‘Went Silent’ Following Rocket Explosion

    Two of Russia’s nuclear radiation monitoring stations went silent two days after a mysterious explosion that led to a radiation spike in northern Russia earlier this month. Russian officials say at least five nuclear engineers were killed during a rocket test involving “isotope power sources” on a platform in the White Sea, leading to outside speculation that the accident involved a nuclear-powered cruise missile. Four international stations designed to monitor nuclear activity had detected “an event coinciding with the [Aug. 8] explosion in Nyonoksa, Russia,” the world’s main nuclear test-ban body said on Aug. 10. The Dubna and Kirov stations...

    The Russian state nuclear agency, Rosatom, said the experts had been testing a nuclear-powered engine. But it gave no further technical details. "These new systems have their origin in Soviet times - they've been taken off the shelves and given new investment." The five nuclear engineers who died were "elite" experts and "heroes" who knew of the risks and had conducted previous tests in "extraordinarily tough conditions", senior Rosatom official Valentin Kostyukov said. Soon after the blast the Severodvinsk administration reported a 40-minute spike in radiation in the city, and news of that prompted locals to buy up stocks of...

    A radiation spike in Russia on Thursday may have been caused when one of Vladimir Putin's top secret Zircon hypersonic missiles exploded during tests, reports in the country have claimed today. Radiation levels temporarily soared 20 times above the normal level in Severodvinsk, a city 18 miles from the weapons testing site at Nyonoksa, according to Greenpeace citing the Russian Emergencies Ministry. Moscow has thrown a veil of secrecy over the incident yesterday in the sub-Arctic Arkhangelsk region, which left two dead and reportedly sparked 'panic' and 'hysteria' among residents and a rush to buy iodine from pharmacies. One report,...

    Radiation levels in the water around a sunken Soviet-era nuclear submarine are some 100,000 times higher than normal, scientists have warned, raising fears that the K-278 Komsomolets may still pose a threat 30 years after it sunk. Norwegian scientists have been analyzing the area around the submarine, which came to rest on the floor of the Norwegian Sea after sinking on April 7, 1989. The accident—caused by a fire in the engine room—resulted in the deaths of 42 of the Komsomolets' 69 crew. Most were killed by radiation exposure while waiting for the Soviet navy to rescue them. The 400...

    The crew on a nuclear-powered Russian military submarine prevented a “planetary catastrophe,” according to a top naval officer who spoke at the funeral for the 14 sailors who died during a fire on the vessel. Captain Sergei Pavlov, an aide to the commander of Russia’s navy, said Sunday the sailors “saved the lives of their colleagues, saved the vessel and prevented a planetary catastrophe.” Dmitry Peskov, a Kremlin spokesman, said there were no signs the incident could have caused a larger catastrophe. “As for the reactor, there are no problems with that,” he said. After days of secrecy about the...

    The researchers used a special statistical technique to determine whether deaths from cancer and heart disease likely had a common cause — in this case, the common cause would be space radiation. But their results did not point to a common cause of death. "If ionizing radiation is impacting the risk of death due to cancer and cardiovascular disease, the effect is not dramatic," the authors wrote in their study, published July 4 in the journal Scientific Reports. Still, the study cannot determine whether longer missions would pose different risks. "It is important to note that future missions of deep...

    Astronauts on the ISS spend hours every week cleaning the inside of the station's walls to prevent mold from becoming a health problem. Spores of the two most common types of mold on the ISS, Aspergillus and Pennicillium, survive X-ray exposure at 200 times the dose that would kill a human, according to Marta Cortesão, a microbiologist at the German Aerospace Center (DLR) in Cologne, who will present the new research Friday at the 2019 Astrobiology Science Conference (AbSciCon 2019). Pennicillium and Aspergillus species are not usually harmful, but inhaling their spores in large amounts can sicken people with weakened...

    In November 2016, astronomers watched a young star some 1,500 light-years away from Earth belch out an explosion of plasma and radiation that was roughly 10 billion times more powerful than any flare ever seen leaving Earth's sun. This sudden stellar eruption may be the most luminous known flare ever released by a young star — and it could help scientists better understand the still-murky process of star formation. "Observing flares around the youngest stars is new territory and it is giving us key insights into the physical conditions of these systems," Steve Mairs, an astronomer and lead author of the study, said...

    Border guards seized a British lorry on its way to make a delivery to the Iranian military - after discovering it was packed with radioactive material that could be used to build a dirty bomb. The lorry set off from Kent on its way to Tehran but was stopped by officials at a checkpoint on Bulgaria's northernborder with Romania after a scanner indicated radiation levels 200 times above normal. The lorry was impounded and the Bulgarian Nuclear Regulatory Agency (NPA) was called out. On board they found ten lead-lined boxes addressed to the Iranian Ministry of Defence. Inside each box...
