Many threads have been slammed onto the site-redundancy is good but one can go too far and cause greater harm...
Hopefully those who have no understanding will take the time to gather some-
"What are the types of radiation?
Alpha particles can travel only a few inches in the air and lose their energy almost as soon as they collide with anything. They are easily shielded by a sheet of paper or the outer layer of a person's skin. Alpha particles are hazardous only when they are inhaled or swallowed.
Beta particles can travel in the air for a distance of a few feet. Beta particles can pass through a sheet of paper but can be stopped by a sheet of aluminum foil or glass. Beta particles can damage skin, but are most hazardous when swallowed or inhaled.
Gamma rays are waves of pure energy and are similar to x-rays. They travel at the speed of light through air or open spaces. Concrete, lead, or steel must be used to block gamma rays. Gamma rays can present an extreme external hazard.
Neutrons are small particles that have no electrical charge. They can travel long distances in air and are released during nuclear fission. Water or concrete offer the best shielding against neutrons. Like gamma rays, neutrons can present an extreme external hazard."
Here is the site to learn from-fairly easy to follow for lay people

also for those wanting something else to study(helpful for those who may be or will become first responders):
Communicating Radiation Risks: Crisis Communications For Emergency Responders - Communicating Radiation Risks: Crisis Communications For Emergency Responders. The U.S. Environmental Protection Agency’s pocket-sized guide, Communicating Radiation Risks: Crisis Communications For Emergency Responders, was developed especially for responders and government officials communicating with the public and the media — or advising those who do — during the early critical moments of a radiological emergency. It provides communications techniques and advice based on proven risk and crisis communications strategies as well as radiological scenarios and messages for use in radiological emergencies.
For a PDF copy or printed copies of the guide or information on guide training, please e-mail [email protected] or call the U.S. EPA's Radiation Protection Division at 202-343-9290.
"“Given the large quantity of irradiated nuclear fuel in the pool, the radioactivity release could be worse than the Chernobyl nuclear reactor catastrophe of 25 years ago.” said Kevin Kamps, a nuclear waste specialist.
Fukushima I (there are two plant locations) is one of the 25 largest nuclear power stations in the world.
How would a nuclear plant meltdown unfold?
* Control rods are driven back down into the core upon emergency (if rods don’t make it all the way… trouble)
* The coolant (water) could cease if backup systems fail (electricity, pumps, generators, batteries)
* Reactor continues to produce heat
* Numerous venting valve systems would release pressure above ~1,000 psi into containment vessel
* Eventually the uranium fuel encasement metal will melt (2,200 deg F)
* Radioactive contamination then released into the reactor vessel
* Radiation escapes into an outer, concrete containment building
* Radiation escapes into the environment as radioactive Fallout.
Not only would such a disaster be horrible for the local region and Japan, but other countries, namely the U.S. could be effected next by airborne fallout of radiation particles, the magnitude of which is yet to be determined."
