Först trodde jag att det var ett par kulor eller laddade patroner innan jag la märke till trädetaljerna.
Radiation exposure from radioactive lenses
According to the research (below), radioactive lenses are relatively safe. We are regularly exposed to radiation from various sources every day, which combined give a more significant dose than the use of radioactive lenses would:
Walking around outside in the sun (main contribution to the annual radiation dose)
Staying at home (Radon from the building materials, tiles)
Eating bananas (Contains potassium-40)
Eating brazil nuts (Contains Radium-226)
Flying on an aeroplane (about 2μSv/h of Cosmic radiation)
Getting an x-ray at the doctor
Sleeping next to someone (the other person is radioactive to us (potassium-40)
Having a smoke detector (contains americium-241)
Having a granite countertop (uranium and decay products)
Smoking (releases radium, lead-210, polonium-210)
