Chemistry 112 Lab: Section 005 December 2, 2014 Prelab for Factors Affecting Radiation Intensity 1. Strengthen your “radiation vocabulary”: Define the following terms as indicated (fill in the words or numbers as appropriate). Bq (Becquerel) = One of three units used to measure the intensity of radioactivity in a sample of material. The amount of ionizing radiation released when an element spontaneously emits energy as a result of radioactive decay of an unstable atom. 1 Bq represents a rate of radioactive decay equal to 1 disintegration per second. Ci (Curie) = A Curie is equal to 37 billion Bequerels. A Curie is 37 billion disintegrations per second. Sv (Sievert) = The international system (SI) unit for dose equivalent equal to 1 Joule/kilogram. Named for physicist Rolf Sievert. R (Roentgen) = A unit of exposure to ionizing radiation. It is the amount of gamma or x-rays required to produce ions resulting in a charge of 0.000258 coulombs/kilogram of air under standard conditions. Named after Wilhelm Roentgen, the German scientist who discovered x-rays in 1895.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
