Given initially 40mg of radium-226 (one of the decay products of uranium-238), determine: a. The total amount of kinetic energy that will have been released during that time. b. Find the decay rate of the radium at the end of the 500yrs. c. One of the units used to quantify the health risks of ionizing radiation is a gray, where 1 gray = absorption of 1 joule of radiation energy per kilogram of matter. Exposure to radiation at a dose of 0.7gray or higher causes radiation sickness. How many seconds of exposure to the sample at the end of the 500yrs would result in radiation sickness for an average human (62kg)?
