Question

The Use of Radioactive Radiation (4)

Not quite remember

I easily remember

The use of radioactive radiation in the field of archeology and geochronology (1)

Carbon dioxide in the air is made up of carbon-12 (C-12) which is stable and carbon-14 (C-14) which is radioactive

The use of radioactive radiation in the field of archeology and geochronology (2)

As carbon dioxide is absorbed and released by the body of living organisms, the percentage of C-14 in the tissues of the organisms does not change

The use of radioactive radiation in the field of archeology and geochronology (3)

As soon as the organisms die, the amount of C-14 in their tissues begins to decline because they decay by emitting beta radiation with a half-life, T 1/2 , of 5 700 years

The use of radioactive radiation in the field of archeology and geochronology (4)

By measuring the activity of C-14, the age of the remains can be determined

Example of the use of radioactive radiation in the field of archeology and geochronology

Carbon-14 dating for determine the age of something ancient object.

Example of the use of radioactive radiation in the field of medicine

Treating cancer by killing cancer cells

Example of the use of radioactive radiation in the field of agriculture

Determine the absorption rate of fertilizer phosphate in plants

Examples of the use of radioactive radiation in the field of defense

Build weapons like atomic bombs

Examples of the use of radioactive radiation in the industrial field

Sheet metal thickness control

Symbol of the presence of radioactive material or radioactive radiation
