Hazardous Materials: Class 7: Radioactive ... use and handling of hazardous materials may differ depending on the activity and status of the material. For example ...
Radiation and radioactive substances are used for diagnosis, treatment, and research. X-rays, for example, pass through muscles and other soft tissue but are stopped by dense materials. This property of X-rays enables doctors to find broken bones and to locate cancers that might be growing in the body. [7]
Naturally occurring radioactive materials (NORM) and technologically enhanced naturally occurring radioactive materials (TENORM) consist of materials, usually industrial wastes or by-products enriched with radioactive elements found in the environment, such as uranium, thorium and potassium and any of their decay products, such as radium and radon.

As demand for construction of nuclear power plants increased, it became necessary for humankind to understand how radioactive material interacts with various ecosystems in order to prevent or minimize potential damage. The aftermath of Chernobyl was the first major employment of radioecological techniques to combat radioactive pollution from a ...
Most plutonium and other radioactive material is in concrete or steel structures or underground. And many sites are remote, where public risk likely would be minimal. Still, potential threats have ...
Class 3 Flammable solids, self-reactive substances and solid desensitized explosives – Solids which, under conditions encountered in transport, are readily combustible or may cause or contribute to fire through friction; self-reactive substances which are liable to undergo a strongly exothermic reaction; solid desensitized explosives which ...
