Nuclear pollution

The worldwide production of uranium in amounted to 50, tonnes. The mining and milling of uranium present significant dangers to the environment. The product is a powder of unenriched uranium, " yellowcake ," which is sold on the uranium market as U3O8. Hundreds of abandoned mines, primarily used for the US arms race and not nuclear energy production, have not been cleaned up and present environmental and health risks in many communities.

The radiation release associated with a nuclear disaster poses significant acute and chronic risks in the immediate environs and chronic risk over a wide geographic area.

Radioactive contamination, which typically becomes airborne, is long-lived, with half-lives guaranteeing contamination for hundreds of years. Concerns over potential nuclear disasters center on nuclear reactors, typically those used to generate electric power.

Other concerns involve the transport of nuclear waste and the temporary storage of spent radioactive fuel at nuclear power plants.

The fear that terrorists would target a radiation source or create a "dirty bomb" capable of dispersing radiation over a populated area was added to these concerns following the terrorist attacks on New York City and Washington, D.

Radioactive emissions of particular concern include strontium and cesium, both having thirty-year-plus half-lives, and iodine, having a short half-life of eight days but known to cause thyroid cancer.

In addition to being highly radioactive, cesium is mistaken for potassium by living organisms. This means that it is passed on up the food chain and bioaccumulated by that process. Strontium mimics the properties of calcium and is deposited in bones where it may either cause cancer or damage bone marrow cells.

The Chernobyl Disaster Concern became reality at 1: More than thirty people were killed immediately. The radiation release was thirty to forty times that of the atomic bombs dropped on Japan during World War II. Hundreds of thousands of people were ultimately evacuated from the most heavily contaminated zone surrounding Chernobyl.

Radiation spread to encompass almost all of Europe and Asia Minor; the world first learned of the disaster when a nuclear facility in Sweden recorded abnormal radiation levels.

Chernobyl had four RBMK-type reactors. These reactors suffer from instability at low power and are susceptible to rapid, difficult-to-control power increases.

The accident occurred as workers were testing reactor number four. The test was being conducted improperly; as few as six control rods were in place despite orders stating that a minimum of thirty rods were necessary to maintain control, and the reactor's emergency cooling system had been shut down as part of the test.

An operator error caused the reactor's power to drop below specified levels, setting off a catastrophic power surge that caused fuel rods to rupture, triggering explosions that first destroyed the reactor core and then blew apart the reactors' massive steel and concrete containment structure.

The health impacts of the Chernobyl explosion will never be fully known.

NUCLEAR POLLUTION: NUCLEAR POLLUTION

It is estimated that some three million people still live in contaminated areas and almost ten thousand people still live in Chernobyl itself. The plant itself was not fully shut down until nearly fifteen years after the disaster.

Studies by the Belarus Ministry of Health, located approximately eighty miles south of Chernobyl, found that rates of thyroid cancer began to soar in contaminated regions infour years after the radiation release.

Gomel, Belarus, the most highly contaminated region studied, reported thirty-eight cases in Gomel normally recorded only one to two cases per year. Health officials in Turkey, miles to the south, reported that leukemia rates are twelve times higher than before the Chenobyl accident.Mar 23,  · Nuclear fusion has long been considered the “holy grail” of energy research.

It represents a nearly limitless source of energy that is clean, safe and self-sustaining. Radioactive waste is waste that contains radioactive material.

Radioactive waste is usually a by-product of nuclear power generation and other applications of nuclear fission or nuclear technology, such as research and urbanagricultureinitiative.comctive waste is hazardous to all forms of life and the environment, and is regulated by government agencies in order to protect human health and the environment.
