PPT-P4: Radiation for Life

Lesson 2 Sparks part 2 There are two types of charge What are they An atom has four protons and five neutrons How many electrons has it Friction produces static charge How With reference to the last question Why. The US Environmental Protection Agency EPA is responsible for advising the government on radiation hazards and regulating certain sources of radioactivity in the environment This booklet provides basic facts about radiation science as well as inform Knowledge of subatomic particles has led to many advancements- unfortunately besides the advancements in power plants there has been costs-nuclear warfare and waste. Nuclear Decay. The nucleus-cluster of protons and neutrons-is in the centre of an atom. Radaition. vs Matter Dominance. Radiation vs Matter. Matter energy density and radiation energy density have difference dependence on expansion factor R:. Radiation density falls more rapidly than matter energy density.. Keywords: Half-life, GM Tube, count rate, radioactive . decay, . nuclear power . P2 Topic 6: Benefits and drawbacks of using radioactive materials. This topic looks at:. The changing ideas of radioactivity. Nuclear Material. Half-Life. is the required for of a radioisotope’s nuclei to decay into its products.. For any radioisotope,. # of ½ lives. % Remaining.

Gd. or Cd (leads to secondary . . Radiation is the emission of energy in the form of waves or particles. Radiation that is so powerful that it can remove electrons from atoms is called ionizing.. Examples of types of ionizing radiation are x-rays from medical machines and gamma rays from radioactive substances. . Atom structure. 1. 2. 3. What is the radius of an atom?.
