Medical imaging such as MRI can seem daunting, and perhaps even a little sci-fi.
There are many different types of medical imaging and they all pick up different things.
Cosmic radiation is much higher today than it was during the Apollo era.

On March 11, 2011, a nuclear disaster struck Japan. Translated testimony by the power plant's manager reveals how close the world came to a greater catastrophe -- and how much there is to be learned.
Nuclear reactors line the bank of the Columbia River at the Hanford site in 1960.
During the Cold War, the US built nuclear weapons at a network of secretive sites across the nation. Some are still heavily polluted and threaten public health today.

The Trump administration shelved its plans for a 'bloody nose' attack while the Olympics in South Korea were under way. With the games over, it's time to consider the consequences of a strike.

The Trump administration's push for 'energy dominance' could spur a new wave of domestic uranium production. A scholar describes the damage done in past uranium booms and the visible scars that remain.
Marie Curie in one of her mobile X-ray units in October 1917.
During World War I, Marie Curie left her lab behind, inventing a mobile X-ray unit that could travel to the battlefront and training 150 women to operate these 'Little Curies.'
A recent Canadian trial reports breast cancer over-diagnosis rates of up to 55 per cent, from routine screening mammograms.
October is breast cancer awareness month. Women should know there is no reliable evidence that routine mammograms reduce death from breast cancer, and there's good evidence that they cause harm.
Spend many months attached to the ISS and see how well you grow.
If you want to live on Mars, you're going to need to grow food. Seeds are naturally equipped to handle challenging Earth environments, but how well can they survive what they'll encounter off-planet?
Captain, we’re being pummeled by cosmic rays!

The true radiation risk from commercial flying has nothing to do with security scans. A radiation expert explains how much cancer risk the most frequent of flyers take on when they take to the skies.
Radiotherapy treats cancer by directing beams of high energy x-rays at the tumour.
Getting the right amount of radiation is a fine balance between therapy and harm. A common way to improve the benefit-to-cure ratio is to fire multiple beams at the tumour from different directions.
A study found children are at greater risk of developing later cancers from radiation from CT scans.
In a recent study of almost 11 million young Australians, we showed those exposed to a CT scan before the age of 20 had a small increase in cancer risk in the years after exposure.
In the early stage of Hodgkin’s Lymphoma the disease is curable in more than 90% of the cases.
The incidence of Hodgkin's lymphoma in Kenya isn't known, but new information is emerging to shed light on its prevalence.
Some say cancer-causing chemicals can leak into packaging and into your food.
There is no evidence supporting claims that cooking or heating food in the microwave can give you cancer or food poisoning.
Pocket your phone without worry.

Did your holiday gift list include radiation-shielding undies to protect your privates from cellphone radio waves? A radiation expert explains they're unnecessary – your phone won't affect your fertility.

Back in the early 1900s, if you felt a bit sluggish you could reach for a beverage enhanced with radioactive elements to really add some pep to your step. It wouldn't be a healthy choice, though.
‘A-Day’ marked the first of 23 atomic bomb explosions at Bikini.
Department of Energy
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.
