A storage tank contains a liquid radioactive element with a half-life of 92 years. It will be relatively safe for the contents to leak from the tank when 0.02% of the radioactive element remains. How long must the tank remain intact for this storage procedure to be safe? CELEB The tank must remain intact for years. (Round the base of the exponential function to four decimal places. Then round the final answer to the nearest year as needed.)
