causes of radioactivity

Improper disposal of nuclear wastes can cause radioactive substances to remain in the soil for a long time. These substances cause mutation..

Radioactive Waste - Waste products from nuclear power stations etc. are becoming a serious problem. They should be put where the radiation can do no harm. Unfortunately, there is no way of stopping a radioactive nucleus from emitting radiation. Nuclear energy has some advantages..

Radioactive elements are those, which emit invisible radiations of their own accord. This is called radioactivity. Some typical examples of radioactive elements are uranium, thorium, plutonium, polonium etc. Radiations emitted by radioactive elements consist..

The sewer removed from the sewerage during cleaning is often left on the roadside. This poses several health hazards to the public. Some of these wastes are also classified as hazardous wastes. Hazardous wastes are those that are potentially dangerous and can cause diseases, fire, etc...

In 1986 at Chernobyl, Russia an experiment at the nuclear power station went wrong. An explosion blew open the reactor and released radiation into the atmosphere. Over 6 tonnes of nuclear material escaped causing release of radiation. Radiation, if absorbed by an organism can cause..

>When a nucleus emits radiation it is said to decay. Rays from radioactive isotopes are dangerous to living things but are also useful in variety of ways. Exposure to large amounts of radiation is harmful to health. All radioactive materials should always be handled with care an..

Radioactivity is broadly classified into two categories: a) Natural radioactivity and b) Artificial or Induced radioactivity. If a substance emits radiations by itself, it is said to possess natural radioactivity. If a substance does not possess rad..

Large quantity of solid wastes like unused and rejected chemicals (like calcium carbonate, magnesium sulphate, ferrous chloride, ferrous oxide, radioactive wastes, fly ashes, sludge, press mud, saw dust, bottles, plastic materials) unwanted industrial wastes generated during manufacturing..

Transportation whether in plants or animals is the key to the efficient assimilation of the nutrients that the organisms synthesise, get from their environment or digest. The study of these processes helps us in many ways. The study of transport mechanisms in plants helps us to understand the uptak..

Importance of Studying Transportation - Transportation whether in plants or animals is the key to the efficient assimilation of the nutrients that the organisms synthesise, get from their environment or digest. The study of these processes helps us in many ways. The study of transport mechanisms in..
