Sadly the Japanese disaster of March 11, 2011 came in threes: 1. an earthquake, 2. a tsunami, and 3. a nuclear crisis. We are one connected world. Radiation does not stop at a nation's border. Do care about the people of Japan and also care about yourself in the world you live in by learning these terms so you can follow the news in English and make educated decisions about this monumental disaster.
IAEA (acronym)
Definition: The United Nations' nuclear watchdog is the International Atomic Energy Agency. This organization follows all things relating to nuclear science.
Example: The IAEA has been prodding the Japanese government for more information about the crippled nuclear reactors.
nuclear fusion (n)
Definition: The process by which the sun generates its energy.
Example: In nuclear fision, the atoms come together and fuse.

nuclear fission (n)
Definition: The process by which the nuclear reaction takes place in a nuclear power plant.Example: In nuclear fission, the atoms sub divide and form products such as gamma rays.
Definition: The process by which the nuclear reaction takes place in a nuclear power plant.Example: In nuclear fission, the atoms sub divide and form products such as gamma rays.
nuclear fusion (n)
Definition: The process by which the sun generates its energy.
Example: In nuclear fision, the atoms come together and fuse.
radioactivity (n)
Definition: When a nuclei is unstable, it emits particles or rays which can be dangerous for human health.
Example: Radioactivity has been detected in the tap water in the Tokyo area.
radioactive (n)
to irradiate (v)
Definition: To be exposed to radiation.
Example: Unfortunately three workers at the Fukushima nuclear power plant were irradiated when they stepped in radioactive water and received beta burns on their feet.

Example: Radioactivity has been detected in the tap water in the Tokyo area.
radioactive (n)
Definition: That which gives off radioactivity.
Example: Uranium is a radioactive substance.
Example: Uranium is a radioactive substance.
radiation (n)
Definition: The transmission radiant energy.
Example: The different types of radiation are alpha, beta, and gamma.
Definition: The transmission radiant energy.
Example: The different types of radiation are alpha, beta, and gamma.
to irradiate (v)
Definition: To be exposed to radiation.
Example: Unfortunately three workers at the Fukushima nuclear power plant were irradiated when they stepped in radioactive water and received beta burns on their feet.
uranium (n)
Definition: Number 92 of the periodic table, a naturally occurring element that emits radiation.Example: Uranium can be found in mines and is used in nuclear fuel rods.
plutonium (n)
Definition: Number 94 of the periodic table, the most toxic element on earth.
Example: Fukushima Daiichi reactor #3 runs on a combination of uranium and plutonium.
nuclear reactor (n)
Definition: The piece of equipment in which nuclear fission takes place in order to generate electricity or power. Within the nuclear reactor is the reactor core.
Example: Fukushima Daiichi #1 nuclear power plant has a total of six nuclear reactors on site.
nuclear reactor core (n)
Definition: Within a nuclear reactor is the reactor core which contains the nuclear fuel rods.
Example: Japanese officials are worried that the reactor core of reactor #3 is damaged and leaking radiation.
nuclear fuel rod (n)
Definition: The nuclear fuel rods are contained in the reactor core. Each fuel rod is made up of pellets of uranium.
Example: A nuclear fuel rod is enclosed in a zirconium casing in order to keep the radioactivity form leaking out.
zirconium casing (n)
Definition: The outer cover of a nuclear fuel rod.
Example: A nuclear fuel rod is enclosed in a zirconium casing in order to keep the radioactivity form leaking out.
Example: A nuclear fuel rod is enclosed in a zirconium casing in order to keep the radioactivity form leaking out.
containment vessel (n)
Definition: The steel shell that surrounds a nuclear reactor.
Example: If a containment vessel of a nuclear reactor is cracked, radioactivity will be emitted into the environment.
spent fuel rod (n)
Definition: When a nuclear fuel rod has run out of energy it is used up or spent.
Example: There is fear that the spent fuel pools at the Fukushima Daiichi nuclear power plant are damaged and leaking water, causing the spent fuel rods to be exposed to oxygen and heat up.
spent fuel pool (n)
Definition: A large container of water where the spent fuel rods of a nuclear power plant are kept.
Example: There is fear that the spent fuel pools at the Fukushima Daiichi nuclear power plant are damaged and leaking water, causing the spent fuel rods to be exposed to oxygen and heat up.
recriticality (n)
Definition: When previously spent fuel rods overheat and form a nuclear chain reaction creating fission once more.
Example: There is great fear that the spent fuel pools at the Fukushima nuclear power plant will reach recriticality.
meltdown (n)
Example: There is great fear that the spent fuel pools at the Fukushima nuclear power plant will reach recriticality.
meltdown (n)
Definition: When a nuclear core overheats or if a spent fuel pool is damaged, the nuclear fuel rods can melt. This is a problem because radiation can be emitted.
Example: There is fear that at least three reactors are in the process of meltdown at the Fukushima Daiichi nuclear power plant.
Example: There is fear that at least three reactors are in the process of meltdown at the Fukushima Daiichi nuclear power plant.
sievert (n)
Definition: A measuring system for biological changes from radiation.
Example: Two workers at the Fukushima Daiichi nuclear power plant were exposed to 2-6 sievert of radiation when they stepped into radioactive water.
Definition: A measuring system for biological changes from radiation.
Example: Two workers at the Fukushima Daiichi nuclear power plant were exposed to 2-6 sievert of radiation when they stepped into radioactive water.
cold storage (n)
Definition: A term for when a nuclear reactor or rod is in cold water and is no longer producing fission.
Example: Workers at the Fukushima Daiichi nuclear power plant are scrambling to get the nuclear reactors and spent fuel rods in cold storage.
