Imagine teaching and learning in a classroom where staff members are unaware of radioactive materials leaking ionizing radiation! This article tells of one such instance exposed by an environmental engineer working in Massachusetts. Besides providing some background information about ionizing radiation, this article rings the alarm for teachers to know what is stored in their science labs. If mounted sealed discs of ionizing sources ARE being used, these discs must never be breached or damaged. Disposing properly of ionizing sources must follow state and federal guidelines. Often the ingenuity of a teacher can place students at risk when that teacher brings in known sources of radiation from home. For example, knowing that smoke detectors contain supposedly safe sources of ionizing radiation does not make them safe for instructional use. Unless the approved supply company recommends an ionizing radiation item as safe for school use, teachers should refrain from exposing themselves and their students. Safety is not just simple common sense. Teachers need to know the A, B, Gs (alpha, beta, and gamma) of Radiation if they are teaching about radiation.
