Radiation, in the form of waves or particles, is a type of energy that transfers from one location to another. Exposure to radiation is a common occurrence in our daily lives, with sources such as the sun, microwave ovens, and car radios being among the most recognized. While the majority of this radiation poses no threat to our health, some types do. Typically, lower doses of radiation carry lower risks, but higher doses can be linked to increased risks. Depending on the specific type of radiation, varying precautions are necessary to safeguard ourselves and the environment from its impacts, all while taking advantage of its numerous applications.
What is radiation good for?
Health: Medical procedures such as several cancer treatments and diagnostic imaging methods have proven to be beneficial due to the application of radiation.
Energy: Radiation serves as a means for generating electricity, including through the use of solar and nuclear energy.
Environment and climate change: Radiation has the potential to be utilized for the purification of wastewater and for the development of plant strains that can withstand the effects of climate change.
Industry and science: By utilizing radiation-based nuclear techniques, scientists have the capability to analyze historical artifacts or create materials with enhanced properties, such as those used in the automotive industry.
Types of radiation
Non-ionizing radiation
Non-ionizing radiation refers to radiation with lower energy levels that do not have sufficient energy to strip electrons from atoms or molecules, whether they are in inanimate objects or living organisms. Nevertheless, its energy can cause molecules to vibrate, generating heat. This is exemplified by the operational principle of microwave ovens.
The majority of individuals are not at risk of health issues from non-ionizing radiation. Nevertheless, individuals who have frequent exposure to certain sources of non-ionizing radiation may require specific precautions to shield themselves from potential effects such as heat generation.
Ionizing radiation
Ionizing radiation is a type of radiation of such energy that it can detach electrons from atoms or molecules, which causes changes at the atomic level when interacting with matter including living organisms. Such changes usually involve the production of ions (electrically charged atoms or molecules) – hence the term “ionizing” radiation.
At elevated levels, ionizing radiation has the potential to harm cells or organs within the human body, and in severe cases, it can lead to fatality. However, when utilized appropriately and with the proper safeguards, this form of radiation offers numerous advantages, including its application in energy generation, industrial processes, scientific research, and the diagnosis and treatment of various illnesses, including cancer.
