Just to reiterate Woodkovsky's remarks, combine all the radioactive material ever produced by humans and compare its radioactivity to a single solar flare or CME event. The sun laughs in the face of our radioactive prowess. The ionising radiation coming from the galaxy in general laughs squarely in the face of the sun. The ionising radiation from the universe laughs in the face of the galaxy.

I'm not concerned about contaminating space. I was pointing out that radioactive waste within the lifespan of earth could be one of the signs that humans once lived here
That, and the bones of the royals

which is why I said that we have left stuff on the moon. Hard evidence that will last a long time.
