Question 3 [AC 2.3] Calculation Question Marie and Pierre Curie managed to extract 1 mg of radium from ten tonnes of the uranium ore in 1898. Their samples glowed with a faint blue light in the dark, caused by the intense radioactivity exciting the surrounding air. Calculate a) The decay constant for radium-226 b) The number of radium atoms in a 1mg sample of radium-226 c) The activity of a 1mg sample of radium-226 d) The number of radium atoms from that sample remaining in 2018 (120 years later)
