Applications of radioactive isotopes are varied in several areas of science. It ranges from the field of agriculture to the diagnosis of diseases. Radioisotopes are being widely used in plant nutrition studies and several researches are being conducted in many countries for using radiation sources to preserve certain types of agricultural produce, such as potatoes. However, vital use of radioisotopes is in production of new varieties of plants by radiation-induced genetic changes or by directly stimulating plant growth.

Radioactive isotopes have a variety of applications. Generally, however, they are useful because either we can detect their radioactivity or we can use the energy they release. Radioactive isotopes are effective tracers because their radioactivity is easy to detect. A tracer A substance that can be used to follow the pathway of that substance through a structure. For instance, leaks in underground water pipes can be discovered by running some tritium-containing water through the pipes and then using a Geiger counter to locate any radioactive tritium subsequently present in the ground around the pipes. Recall that tritium is a radioactive isotope of hydrogen. Tracers can also be used to follow the steps of a complex chemical reaction.
The ability to precisely date, or identify the age of an object, can teach us when Earth formed, help reveal past climates and tell us how early humans lived. So how do scientists do it? Radiocarbon dating is the most common method by far, according to experts.
Radioisotopes of elements have a wide variety of uses. Every living organism contains the radioisotope carbon Carbon is formed when neutrons from cosmic radiation collide with nitrogen atoms in our atmosphere forming protons and carbon atoms. Carbon dioxide is responsible for carbon entering the food chain.
