This piece is simply a Geiger counter on a pedestal. It beeps intermittently when it detects the low levels of radiation that surround us all of the time. Scientists do not have data about the impact of low levels of radiation on human lives; they can only guess how it affects biology based on what we know about high level exposure, like the atomic bomb. The "linear no-threshold model" is used internationally to gauge radiation exposure safety, and it suggests that a lifetime dose of this background radiation is harmful. For this reason the model is controversial, because we don't have conclusive evidence that such harm occurs. Some scientists argue that these low levels are actually good for us, or even necessary to sustain life. Ultimately we just don't know; Irradiated Air won't let you forget or ignore that reality.
