Africa is blessed with an abundance of sunshine.Given the heavy demand for energy, alternatives, such as solar, could provide solutions and help stimulate economic growth.
The average age of survivors is now 80. In five years, very few of these first-hand witnesses will be around to remember the event. Many of their stories are in danger of being lost forever.
The first atom bomb test seventy years ago today marks the start of a change in Americans’ thinking about radiation. On balance, our nuclear anxieties endure today.
Radiation in space could lead to cognitive decline.
Space weather impacts many modern-day technologies. But one of the most concerning – and least reported – space weather effects is the increased radiation exposure to passengers on commercial long-distance…
A world-first computer model that simulates cancer growth has been developed by an Australian PhD student. The device has…
Every job comes with risk and for those who work in the nuclear power industry the long-term risk of cancer is small but significant. Last decade, research looking into the prevalence of cancer in nuclear…
On the weekend, a tank of radioactive material leaked from the closed Ranger uranium mine in the Northern Territory. While this has prompted concerns about the health of the surrounding Kakadu National…
You may have seen yesterday that Iran has agreed to scale back its nuclear program for six months after two years of economic sanctions in an effort to halt, or at least alter the course of, its nuclear…
Radiation is everywhere. We catch it from the sun’s rays in the sky, and from the rocks beneath our feet. It comes from television sets, radios and mobile phones. We absorb it from certain fruits, vegetables…
Last week’s crisis at the Fukushima nuclear power plant in Japan saw radioactive water leak again from the crippled facility, raising fears that groundwater flowing into the Pacific Ocean could be contaminated…
Just over two years after the disaster at the Fukushima nuclear power plant in eastern Japan in March 2011, public attitudes worldwide remain hardened against nuclear power. It may have fallen from the…
The recent case of Neon Roberts and the legal dispute over his treatment for a brain tumour threw the spotlight on the potential risks of using radiotherapy to treat complex cancers in children. Radiotherapy…
Pacific bluefin tuna affected by radiation released at Fukushima following Japan’s 2011 nuclear disaster have allowed scientists…
NASA revealed this morning (AEST) that its Van Allen Probes have discovered a third, previously unknown, radiation belt around Earth. The belt appears to be transient, depending strongly on solar activity…
SAVING THE OZONE: Part three in our series exploring on the Montreal Protocol on Substances that Deplete the Ozone Layer – dubbed “the world’s most successful environmental agreement” – explains why we…
Most fairly well educated people recognise pseudoscience as bunkum when they see it — astrology, young-earth creationism, alien abduction, pyramid power … Yet some of these same people are now being sucked…
People who received frequent dental x-rays as children could be at increased risk of developing a commonly diagnosed primary brain tumour, according to a study of almost 2,800 people. The study, published…
A year can be a long time in politics. But for the radioactive particles released from Fukushima’s damaged nuclear reactor, a year is just a moment in their life of hundreds or thousands of years. So…
