Don't panic, but your avocado is radioactive: Study eyes radiation of everyday objects
Most people assume all radioactive materials are dangerous, if not deadly. But a new study on the radiation emitted by everyday objects highlights the fact that we interact with radioactive materials every day. The goal of the work is to give people a frame of reference for understanding news stories or other information about radiation and nuclear safety. Ref. Source 7l.
External radiation is encountered every day on many levels. The amount of external radiation can be very high as our skin has grown resilient to the constant bombardment from our every day interactions. The real threat of radiation comes from internal radiation, wherein someone ingests a 'hot particle' which then remains in the tissue, irradiating the surrounding cells.
