Irradiated refers to the process by which something is exposed to radiation, whether in the form of electromagnetic waves (like ultraviolet, X-rays, or gamma rays) or energetic particles. This exposure can alter the physical or chemical properties of a material, destroy microorganisms, or be used for medical treatments. The nature and intensity of the radiation, as well as the duration of exposure, are crucial factors determining the effects of irradiation. These effects can vary from simple heating to significant structural changes, genetic damage, or sterilization, depending on the substance being treated and the type of radiation used. Common applications include food preservation, medical sterilization, cancer therapy, and industrial material modification.
Irradiated meaning with examples
- The hospital sterilized its surgical instruments with a strong dose of irradiated gamma rays to eliminate any potential bacterial contamination. This method ensured a completely sterile environment, protecting patients from dangerous infections. This process is far more effective than traditional sterilization methods in hospitals. This helps with reducing the need for extensive antibiotic use and overall improving patient outcomes.
- The scientist tested a new polymer that was irradiated with ultraviolet light to harden it. The polymers changed chemical structure was found to increase the materials tensile strength making it more resistant to high impacts. The research team was hoping the results would lead to new advancements in product manufacturing. This process is commonly used in the creation of durable components for various industries.
- Food companies sometimes irradiate certain foods to kill bacteria and extend their shelf life. The irradiation process helps to prevent spoilage. The food is then safe to eat longer after processing and shipping to distribution centers. This treatment is used on items such as fruits, vegetables, and spices. The radiation is safe and leaves no traces.
- Patients undergoing radiation therapy are irradiated to target and destroy cancerous cells. The high-energy radiation damages the DNA of the tumor cells, which kills them. The radiation therapy is highly targeted, focusing on the location of the cancer. The aim of this treatment is to destroy the cancerous tissue while minimizing damage to the surrounding tissue.
- The spacecraft's onboard computer systems were shielded to protect them from the damaging effects of space radiation. The constant exposure to the electromagnetic radiation in outer space. A spacecraft being irradiated could lead to component failures and potential mission failure. Effective shielding is critical for the long-term performance and safety of deep-space missions.
