Radioisotopes, or the radioactive isotopes, are atoms containing unstable nuclei discharging radiation through radioactive disintegration. Despite their potential hazards, these radioisotopes are valuable across different sectors such as medicine, industry, agriculture, and the environmental field.

In this article, we will discuss about various real life applications of radio isotopes.

What are Radio Isotopes?

Radioisotopes are simply known as radioactive isotopes that have an element which have an unstable nucleus and thus emit radiation as they undergo decay to attain a more stable form.

For the radiative element, it means that the nucleus is unstable and therefore is inclined to decay and become more stable. This, however, involves emission of particles and electromagnetic radiation such as alpha, beta, gamma rays or positrons.

Real Life Applications of Radio Isotopes

Isotopes of radioactive elements provide multiple techniques involving diagnosis and treatment in medicine, characterization of materials and processes in industry, fertilization and pest control in agriculture, etc. Few of the real life applications of radio isotopes are discussed below:

Cancer Therapy and Treatment

In cancer therapy, radioisotopes play a dominant role in the accurate destruction of cancer cells without damaging the healthy tissues. Radiation therapy strategies, for example brachytherapy and external beam radiation therapy, give controlled doses of radiation in a precise manner to cancer cells which then leads to their destruction.

Example: Iodine-131 is widely applied for the treatment of thyroid cancer; where it selectively gathers in thyroid cells and emits beta radiation, effectively destroying cancerous tissue.

Medical Imaging and Diagnosis

Without radioisotopes, medical imaging and diagnosis would be greatly undermined and would not be able to provide the in-depth study inside of the human body. Radioactive tracers are utilized in nuclear medicine to perform both PET scans and SPECT scans in order to visualize organs, tissues and physiological processes.

Example: In PET imaging, the radioisotopes like the carbon-14 or the fluorine-18 are used to make glucose molecules, fluorodeoxyglucose (FDG) is then injected in the patients’ body. PET scans work by the detection of positron emission. The generated image is highly detailed and depicts the metabolic activity of the tissues.

Industrial Applications

Radioisotopes used in various industrial applications, they are mainly for quality control, materials testing and process optimization. Radioactive tracers are used for the monitoring and analysis of manufacturing processes like oil refining, chemical synthesis, and pipeline inspection. The result is usually a product of high quality, efficiency, and safety.

Example: Within petroleum industry – gamma radiography sources are used by means of of cobalt-60 radioisotopes to spot the defects in pipeline and storages tanks welds.

Agricultural and Food Safety

Radioisotopes are vital players in the agricultural and food safety industry, which includes soil fertility analysis, pest control in the crops, and food preservation. With the help of radioactive tracers, it is possible to research plant metabolism, nutrient uptake processes and soil dynamics. Radioactive tracers enable farmers to improve the crop management and productivity.

Example: Carbon-14 is a regularly adopted method of radioactive isotope for dating techniques for determining the age of archaeological artifacts and geological samples by measuring the amount of carbon-14 decay.

Environmental Monitoring and Research

Radioisotopes are valuable tools for environmental monitoring and research. Scientists use them to trace pollutant sources, natural processes that occur like degradation of substances, and assessment of impacts. Radioactive tracers are used to trace the pollutants movement among air, water, and soil, offering valuable information on ecosystems and environment.

Example: Tritium, a radioactive isotope of hydrogen, is an indicator of water flow direction in hydrological studies including rate of aquifer recharge and contaminant pathways.

Sterilization in Healthcare

Radioisotopes are used in healthcare for the sterilization of medical equipment, pharmaceuticals, and biological specimens. Gamma rays expelled by radioisotopes like cobalt-60 and cesium-137 can effectively kill micro-organisms include bacteria, viruses, and fungi. Therefore, the sterilization process is both effective and reliable.

Example: Gamma irradiation has become a standard mode of sterilization for disposable medical supplies such as syringes, surgical gloves, and bandages, etc.

Oil and Gas Exploration

Radioisotopes enable oil and gas production through the investigation of oil and gas reserves while geological surveys, reservoir characterization, and well logging are performed. Radioactive tracers, like logging tools and gamma ray loggers, are powerful sources for subsurface rock formation studies, fluid flow parameters and reservoir connectivity.

Example: Well logging uses neutron-activation analysis so as to define the elemental makeup of the formations and to forecast an oil potential.
