This year saw nuclear weapons tested, stockpiles renewed, and disasters remembered.
A doll lies in the ghost town of Pripyat, abandoned since the nearby Chernobyl power plant suffered a catastrophic meltdown in 1986.
The Royal Commission into Institutional Responses to Child Sex Abuse has documented heart-rending testimonies and elicited shattering revelations. But how does a society witness itself failing at its most fundamental duty?
Disaster tourism and obsessions with sites of death and destruction can be a learning experience, not just voyeurism.
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.

How do we measure long-term impacts of nuclear accidents? Studies at Chernobyl and Fukushima show that radiation has harmed animals, birds and insects and reduced biodiversity at both sites.
Pripyat is often portrayed as a haunted ghost town.

Chernobyl's liquidators have come up with some intriguing ways of dealing with what they've gone through – without directly confronting painful memories.
Engineers have devised an innovative way to dismantle Chernobyl's reactor while preventing further radiation escaping.
Because knowledge is power.
Small nuclear reactors are one step closer to powering the UK's future energy requirements.

Estimating health impacts after a nuclear accident is more complicated than you might think.

The nuclear operator was nowhere near adequately covered for the disaster. And it's not just a Japanese problem.
Nobel Prize for Literature winner Svetlana Alexievich.
Employing a unique literary method that blurred the genres of oral history and documentary prose, the Nobel Prize for Literature winner told the stories of a traumatized people.
Giving voice to the voiceless.
The Belarussian is a worthy winner, but the Nobel is getting further and further away from its lofty origins.

Any nuclear weapon exchange or major nuclear plant meltdown will immediately lead to a global public health emergency. What can we learn from past events to help prepare?
The Fukushima disaster was a dark chapter for nuclear power - but high-profile accidents are far from the only downside.
Is nuclear power worth it? No, says Mark Diesendorf – it's never been a major world energy force, it has caused huge accidents, and its greenhouse emissions are higher than many people realise.
You can try and control it, but radiation is everywhere.

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…
