Chemistry: An Introduction to General, Organic, and Biological Chemistry, Eleventh Edition Copyright © 2012 by Pearson Education, Inc. Geiger Counter A Geiger counter detects beta and gamma radiation uses ions produced by radiation to create an electrical current 2

Chemistry: An Introduction to General, Organic, and Biological Chemistry, Eleventh Edition Copyright © 2012 by Pearson Education, Inc. Units for Measuring Radiation Units for measuring radiation activity include Curie – measures activity as the number of atoms that decay in 1 second rad (radiation absorbed dose) – measures the radiation absorbed by the tissues of the body rem (radiation equivalent) – measures the biological damage caused by different types of radiation 3

Chemistry: An Introduction to General, Organic, and Biological Chemistry, Eleventh Edition Copyright © 2012 by Pearson Education, Inc. Measuring Radiation Activity Often the measurement for an equivalent dose is in millirems (mrem). One rem is equal to 1000 mrem. The SI unit is the sievert (Sv). One sievert is equal to 100 rem. 4

Chemistry: An Introduction to General, Organic, and Biological Chemistry, Eleventh Edition Copyright © 2012 by Pearson Education, Inc. Radiation Exposure Exposure to radiation occurs from naturally occurring radioisotopes medical and dental procedures air travel, radon, and smoking cigarettes cosmic rays 5

Chemistry: An Introduction to General, Organic, and Biological Chemistry, Eleventh Edition Copyright © 2012 by Pearson Education, Inc. Radiation Sickness LD 50 is the amount of radiation to the whole body that is the lethal dose for one-half the population varies for different life-forms, as Table 9.6 shows 6
