You're putting words in my mouth. The comparison is that the radioactivity of some of the medical isotopes is by far higher than in the steam generator, and it's not the technetium, it's the moly that has a longer life. And there's cobalt and uranium and yellowcake, and there is gauge. Yes, millions of radioactive materials are being shipped every day across the whole world with a higher radioactivity than a steam generator.
