Los Angeles has high levels of nuclear radiation from Susanna Labs (Rocket Dyne, NASA) is there anything that can block strontium-90 or Celesium from being absorbed into the body. I was just reading about how they use methylcyclopropene to block the formation of ethylene by fruits so they don't ripen and it occurred to me maybe something could be done for nuclear waste. Thyroid cancer is the number once cancer children are getting here, and it come from exposure to radiation.
