Why would it kill off megaladon but not whales?

Random spitball idea: A giant carnivore is much more vulnerable to a food-web collapse than a giant generalist.

They claim the reason it died out was because its large size made it receive a higher dose of radiation from supernovae than smaller animals causing it to be vulnerable to higher mutation and cancer rates. But other large marine animals from the same era survived to become modern marine mammals.
