      Yes, our bodies are naturally radioactive, because we eat, drink, and breathe radioactive substances that are naturally present in the environment.

      We have around 0.3 mSv (millisievert) of radiation in our body, which equals to the radiation of 3,000 bananas!

      To add on Mako – We consume radiation through food too and we are bombarded by radiation from space too! But our bodies are quite resilient and have evolved with radition present for millions of years.
