Is this a glitch? Because I was Mining and then ate a few cookies to get rid of some of the hunger and then i got hurt and nothing was hitting me so i looked into my invent and i had one block of that freaky Radioactive Material and then grabbed the Haz-mat Suit and got no more hits from radiation. Honestly i looked it up on the wiki but it wasn't there so i googled it and found this site. What has been said really freaked me out in the fact that this has gone haywire.
