Although it can be destructive, radioactivity is also beneficial, especially when it comes to medical tests and certain medical treatments. Not only can radiation find tumors within the body, it can also destroy them or slow their growth. Without radiation, society would not have medical imaging technology, such as X-rays. Radiation also makes it possible to study matter, plants and animals in an effort to understand the universe better.Know More
Radiation can also be used to create electrical energy. Nuclear reactor plants are located all over the country for this purpose. These plants use uranium in fission reactions to produce heat and steam. The steam is then used to turn a turbine, thus creating electricity.
Additionally, radiation can be used to clean and sterilize medical equipment, medical instruments and even food. This is accomplished by focusing concentrated beams on objects that need to be sterilized. The radiation kills bacteria and other organisms that cause contamination and disease. Since sterilization is performed using certain types of radiation along with electromagnetic energy, there is no residual radiation leftover to contaminate the objects.
While radiation has many benefits, too much of it can kill people, animals, plants, trees and any other living thing it comes into contact with on Earth. This is especially true if there is prolonged exposure.Learn more about States of Matter
Marie Curie discovered two new elements of the periodic table (polonium and radium) and conducted extensive research on radioactivity. She was the first woman to receive a Nobel Prize. Marie Curie was also involved in the development of X-ray machines.Full Answer >
Scintillation counters are important tools for detecting and measuring radioactivity. They work by exposing radioactive materials to atoms within the detector that temporarily absorb the radiated energy. These excited atoms return to their unexcited state and emit photons that are detected by the scintillation counter.Full Answer >
Thickness, length and temperature are the three factors understood to affect a material's property of resistance in conduction. These factors are also affected by the material in use, though this is accounted an independent influencing factor.Full Answer >
An application of Charles' Law is a floating hot air balloon. A torch heats the air inside the balloon causing the air particles to move faster and disperse, making the air in the balloon less dense than the surrounding air so that the balloon floats.Full Answer >
