How does nuclear radiation affect the human body?
Over the last few weeks, "above-legal" levels of radioactive iodine-131, caesium-134 and caesium-137 have been detected in marine life off the coast of Japan.
And more recently, plutonium and strontium-89 and strontium-90 have been detected in the soil around the damaged Fukushima nuclear plant.
The amount of radiation harmful to people depends on which chemical element, and how much of it they are exposed to, says Steven Crossley, a radiation physicist at Sir Charles Gairdner Hospital in Western Australia.
Different variations of elements, known as isotopes, decay by different methods and give off different types of radiation, so they can have different effects on the body, he says.
In a reactor when neutrons are smashed into an atom, the atom releases neutrons which then hit other atoms in a chain reaction (find out how nuclear reactors work ).
The bits of smashed atom (fission fragments) are unstable isotopes that become stable by releasing energy as ionising radiation.
What is ionising radiation? Ionising radiation has enough energy to remove electrons from atoms. It can cause damage by breaking chemical bonds. Types of ionising radiation include:
Alpha particles — two protons and two neutrons bound together like a helium nucleus — are large particles that can do lots of damage, but only over short distances.
Beta particles — are electrons, which can travel longer distances in air and tissue than alpha particles.
Neutron radiation — consisting of free neutrons which are released during fission but not usually through radioactive decay.
Gamma or x-rays , which are electromagnetic radiation similar to light, but with much more energy.

According to Crossley, there are two ways you can be exposed to radiation.
"External irradiation is when you absorb the energy of radiation which can be in the form of beta, alpha or neutron particles or as gamma and/or X-rays. But it only lasts as long as you're near the source, once you move away, you are not being irradiated any more."
"You don't become radioactive from external irradiation", says Crossley.
"Contamination is when you get the radioactive material itself on you or in you, including eating it breathing it in or absorbing it through the skin.
