Here are some FAQs
Why isn’t the monitor outside?
We keep the Inspector inside so we can light it easier for you to be able to see 24/7. There is no need to have it outside or face it into the wind. The kind of radiation we’re looking for at first with fallout that may travel across the Pacific Ocean to Southern California is gamma radiation.
Gamma travels great distances and goes through just about anything, including you and me. Lead will stop it. In fallout, one the primary radionuclides of concern is iodine-131 which emits a lot of gamma radiation but is a beta emitter as well. If we left the Inspector outside and fallout begins to come down, the beta emitting I-131 could contaminate the instrument. Even without contamination issues, measuring it inside or outside, if at the same elevation, location and not over concrete (which has some uranium in it which skews the readings higher), is the same.Read the rest of the article on: EnviroReporter
