Many important economic and social benefits are derived from the use of radio isotopes and radiation. Applications of radiation are found in industry, medicine, agriculture as well as in space exploration.

The oldest and best known use of radiation is for medical diagnosis by X-rays. They penetrate the man's body to dif­ferent degrees and shadows of bones and other materials appear on a photographic film.

In industry a fabric can be made soil-resistant, a new type of wood and tiles can be produced.

Radiation finds application in crime investigation, in agriculture for selection of better seeds and for food preser­vation.

The probable age of a piece of art can be determined by testing the paint.

Radiation methods can be of great benefit to history, archeology and anthropology as well, since they can be used to establish dates and events. The determination of the age of minerals in the earth, in meteorites, or on the moon can also be made. The technique is of particular interest in determining the date of the first appearance of man.
