Radiation 2 Figure 1. Radioactive Substance How Mu.
This lesson will define background radiation, explain how it is measured, discuss some of the sources and examples of background radiation, and briefly consider the risk to humans.Background Radiation. Humans are exposed to radiation all the time. This radiation is called background radiation. Most of the background radiation the body is exposed to is from natural sources and is called natural background radiation.A small amount of the background radiation is from artificial sources and is called artificial background radiation.Radiation 2. Figure 1. Radioactive Substance. How Much Radiation Are We Exposed to? Radiation is often associated with glowing green slime as shown in Figure 1, but this is a very inaccurate representation as radiation is invisible.We are constantly exposed to low doses of radiation even if we are not aware of it.
Question: Short Answer Radiation Experiment 1: Measure Background Radiation Lab Results What Did The Geiger Counter Read As The Count For The Background Radiation? 40 Experiment 2: Measure Radiation Emitted By Radioactive Sources Lab Results Record The Total Radiation Emitted By Each Of The Samples In The Table Below. Sample Recorded Radiation (cpm) Alpha Radiation.Read below the map! Depending on your location within the US, your elevation or altitude, and your model of Geiger counter, this background radiation level might average anywhere from 5 to 60 CPM, and while background radiation levels are random, it would be unusual for those levels to exceed 130 CPM.
Radiation Part I 1. What was the level of background radiation you observed? 40 was the radiation number when Geiger-Mueller was on the work bench. 2. What are some of the sources of background radiation? The Americium-241, Fiesta plate, Glow stick, Smoke detector, Salt, and Lantern Part II 1. Record the radiation emitted from each of the materials.
