In the summer of 1946, the U.S. government detonated the first of many atomic bomb tests in the Marshall Islands. Seventy years of radiation exposure later, residents are still fighting for justice.
Tim Peake, Yuri Malenchenko and Tim Kopra are about to return to Earth after a six-month stay at the ISS.
In theory, astronauts get the equivalent of a lethal x-ray dose during a six-month stay at the ISS. Here's why we don't have to worry too much though.
There is still no firm evidence that mobile phones cause cancer.
Don't throw away your phone quite yet. There are a lot of unanswered questions surrounding the latest study that found a connection between mobile phones and cancer.
Australia could take spent fuel from nuclear power stations overseas. This one is in South Korea.
South Australia's Nuclear Fuel Cycle Royal Commission has recommended a nuclear waste site for the state.
Radiation exposure as a child can increase cancer risk later in life. But by how much?
Chernobyl is already responsible for up to 5,000 cases of cancer in Europe.
After one reactor at the Chernobyl nuclear power plant caught fire and exploded in 1986, the whole site was encased in a concrete sarcophagus.
The meltdown at the Chernobyl Nuclear Power Plant in 1986 exposed 572 million people to radiation. No other nuclear accident holds a candle to that level of public health impact.

Estimating health impacts after a nuclear accident is more complicated than you might think.
Elementary school students about 13 miles from the Fukushima Daiichi nuclear power plant walk past a geiger counter in 2012.
Remediation will never get radiation to zero in the area affected by the 2011 meltdown at the Fukushima-Daiichi nuclear power plant. Rather than safety, the conversation should focus on acceptable risk.
There is no firm evidence that mobile phone radiation causes us harm.
ABC's Catalyst episode "Wi-Fried" claimed that mobile phones and Wi-Fi might be a cancer risk, but the leading experts are not so convinced.
Polonium is found naturally in uranium ore.
Polonium's chemical properties made it the ideal secret weapon for the assassins of Alexander Litvinenko.

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.
Blowing up the desert – and people’s minds: the first atom bomb test in 1945.
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.
I really hope this is the right flag.
Radiation in space could lead to cognitive decline.
Like Icarus, passengers on aircraft during solar flares can cop the effects of flying close to the sun.
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…
Not all radiation is harmful.

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…
Don’t be confused: here’s the difference between radiation and radioactivity.
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…
