- Wrong. Radioactivity in the home is NO hazard. Nothing
- encountered in the household (unless you happen to have a
- teletherapy unit in your garage) presents a radiological hazard
- OR threat. Gross ignorance of the nature of radioactivity
- coupled to such "spreading of the word" leads to the worries
- that border on hysterical, as we've seen here.
-
- Dave, you ought to know better. Let's try a little test. Put
- the following in ascending order of radioactivity. Then put
- the list in ascending order of radiation emittance. Identify
- the active isotope in each and the approximate quantity. For
- extra credit, note where, if ever, on the list a radiation
- health hazard becomes apparent. Cite the applicable NCRP or NRC
- reference for your assertion.

-
- It's treated differently because people who should know better cite
- radioactive sources emitting tens of millions of times less radiation than
- that which causes any known or suspected effect and then call them
- hazards. The trace radioactivity in the home is no more hazardous than
- the trace arsenic, cyanide, heavy metals and other stuff found naturally
- in food. Worrying about the activity in a smoke detector is about
- like worrying about the cyanide in an almond.
