Well it’s been filtered for all radioactive material except tritium and is well below the level of concentration the UN allows for drinking water. They are not detecting any radiation currently and and releasing the water very slowly over 30 years. Did you just not read the article or what?
Well also if something is supposed to be tamper evident they have a (usually legal) incentive to make sure it stays on a all times. They don’t do the testing to find the best sticker adhesive or what is easiest for the consumer because at the end of the day they need it to do one job. You could easily find the best adhesive for the material you are using that stays on very well and can be removed without leaving residue or damage behind. You may have to pay 2 times as much for a better sticker anyway. Not worth the time
