31. Use the following information to answer the next 2 question Natural gas is often found trapped in layers of shale that contain large amounts of radioactive potassium. As the potassium isotopes decay, they emit gamma radiation. When drilling to find natural gas reserves, geologists may look for high levels of gamma radiation from rock layers, Gamma Decay of Potassium-40 and Associated Nuclide Masses Potassium 40 Isotope Decay Nuclide 0 Mass 0.000 549 39.964 00 39.962 383 1 (x10 kg/mol) Numerical Response As shown above, the change in mass that occurs during the radioactive decay of 1.00 mol of potassium-40, K, expressed in scientific notation, is-a.be x 10-6 kg. The values of a, b, and e are and 32. (Hint: you might have to use your data booklet for this question) The instrument that a geologist uses to detect the gamma radiation in a shale layer would be most sensitive to electromagnetic radiation with a wavelength of A. 400 nm B. 700 nm C. 1.56 x 10-¹2 m D. 2.31 x 1021m
