radioactive word

Took a friend for a PET scan this morning. Apparently they pump you full of radioactive material which fires off positrons that get measured by the imaging equipment. He was told leaving the hospital not to stand close to any pregnant women or young children for the next 8 hours as he is still emitting positrons all over the place! I had lent him my Bible to read while he waited for the medication to get fully into his blood stream. So I guess this means that my Bible albeit in a small part could now radioactive too! Brings a whole new meaning to Hebrews 4: 12!
