By "nuclear leaks" is meant the leakage of radioactive material from a nuclear facility such as a nuclear reactor or a store of spent fuel. This would only happen if the fuel had been damaged and the zircaloy sheathing was leaking, and also the contents of the reactor or store were leaking into the atmosphere. The leaked material could be gaseous like iodine, or could be particulate.
The recent Japan earthquake and tsunami, damaged several of Japan's nuclear power plants. These have leaked and are still leaking radioactive isotopes into the surrounding environment where they will pose a health problem to the people of Japan for many thousands of years.
The Fukushima Daiichi nuclear power plant in Japan was severely damaged by the earthquake and tsunami that hit in March 2011. The event resulted in the release of radioactive materials and led to one of the worst nuclear accidents in history.
All nuclear fuels contain radioactive elements.
A nuclear power plant is considered safe and does not emit toxic fumes into the air. However, in case of a disaster such as an earthquake, a nuclear power plant may be damaged and it will leak radioactive particles into the air.
Nuclear fuel rods are dangerous because they contain radioactive materials that can emit harmful radiation when not properly shielded. If the rods are damaged or not handled correctly, there is a risk of a nuclear meltdown or release of radioactive material into the environment, which can cause severe health and environmental consequences. Proper storage and disposal of nuclear fuel rods are necessary to mitigate these risks.
Because it is supposedly leaking radioactive materials and is not up to safetly standards since it is so old.
no, but the products of fission are radioactive
Some isotopes of cesium are radioactive and synthetic, as indicated in recent news reports about the Japanese nuclear reactor damaged by the recent severe earthquake/tsunami. (The radioactive cesium reported was formed by atomic fission of uranium and/or plutonium in the reactor.) However, most cesium is neither radioactive nor synthetic!
Nuclear
Nuclear fusion and nuclear fission are processes that involve nuclear reactions but are not examples of radioactive decay. Chemical reactions, such as burning wood, do not involve nuclear processes and are also not examples of radioactive decay.
