Brett Kerbey and Abhi Prakash What is radiation? It is the release of energy as electromagnetic waves or moving as subatomic particles at high energy frequency. What subatomic particles in the atom determine whether or not the atom is radioactively unstable? The electrons are what determines whether or not an atom is radioactively unstable. The electrons will shift in quantity until it reaches equilibrium, it will do this by either gaining or losing electrons. This process of moving towards equilibrium is known as Natural transmutation. What part of an atom is involved in radioactive decay? The nucleus of an atom (Sinha). Compare and contrast alpha, beta, and gamma radiation. Alpha radiation is the weakest, as far as it’s ability to penetrate matter. It can not break through paper, or even dead skin cells. However, if it is ingested or gets into food it can be deadly. Beta radiation is the second weakest, it can travel further up in the air due to its small mass, however it has low piercing power and can break through paper, but will be stopped by plastic or a stack of papers. Gamma radiation is the most powerful one listed, it does not consist of any particles unlike the other two. As it has no mass, it can travel very far through air and can pierce almost anything except for lead or iron. What gives off radiation? The sun gives off radiation and that is why our atmosphere is very important, it acts as a shield for the earth and protects us from harmful thing waves which are emitted from the sun. A natural occurring process involves a tree which produces a nut called “the brazil nut.” The nut is radioactive but not enough to give you physical mutations. The reason why the nut is radioactive is because the roots of the tree grow deep in the ground, collecting an element called Radium. Any product that is releasing energy as electromagnetic waves or subatomic particles, a product can also begin to give off radiation due to coming in contact with a radioactive product. As we examined in our lab with the geiger counter, there are multiple sources of radiation in our everyday lives, and although it may not be harmful, it is still there and the focus of our unit in Spire is discuss the available options we have to make this product useful. Are you exposed to radiation in your everyday life, if so what sources? Exit signs which you may see at your workplace, school and shopping center have radioactive isotopes, often in the form of neon. This is because if the signs were connected to the main power system, and there was an outage the signs would also go out, the radioactive isotope

Brett Kerbey and Abhi Prakash energy is used to emit the dotted “glowing red/green” light. Many foods also contain radiation, bananas (due to the fact that they have potassium) are slightly radioactive. Potassium is used in your body so it does not have any affect on your nervous system or physical features. The most common food that we know of that contains high-levels of potassium is the banana.
