Are You Exposed to Radiation?

"If you're a kid, we're especially careful about exposure to radiation because you have a much longer life ahead of you and the risk is greater," he says. "It's not that they say it's okay in old people. It's more that it's just like you have to be especially careful in young people." He adds: "I always click over to the idea like we're lucky that incredibly smart people figured out how to use radiation to our benefit"
