Your household alarms can cause radiation poisoning!

Radiation can make any homeowner uneasy. Visions of radioactive leakage, cancer, and poisoning might come to mind — things we would rather stay clear of. Employing radioactive material as part of smoke alarm technology might seem odd at best; how could such a dangerous substance possibly ensure home protection? In this article, we address this challenge head-on by outlining exactly why radioactive substances are employed and any adverse consequences this might have for us all.

Most household detectors contain only trace amounts of americium-241, a radioactive isotope. Any amount measured outside the unit does not present any health risk — in fact, the annual radiation dose from these devices represents less than 0.01 percent of natural background radiation levels for one individual! Such sources do not produce radioactivity that could make other substances radioactive!

Yes!! You heard the right answer! It is a complete myth that smoke alarms can cause radiation poisoning! These devices remain completely safe even during and after fire incidents, thanks to their safe encasements and minimal radioactive material content.

Smoke alarms in Australia by various recognized brands use isotopes of americium as alpha particle emitters, and since alpha particles are easily stopped by most physical materials, nothing significantly hazardous will escape from their chamber in the detector, which holds only trace amounts — approximately one microcurie — of radioactive material.

If you were to break open and consume an americium-laced chamber, most would be expelled from your body within days, while some traces might remain in bones, gonads, or liver and slightly increase the risk for cancer development, although short-term death would not likely occur as a result.

Let’s now discuss what radiation poisoning is!

Assuming we’ve established that smoke alarms do not lead to radiation poisoning, let us introduce what radiation poisoning is and its effects.

Radiation poisoning, commonly referred to as “acute radiation syndrome” or “radiation sickness, refers to any damage done to your body due to exposure to excessive radiation in a short amount of time. How sick you will get from radiation depends upon how much of it your body absorbs, and you won’t get radiation sickness from receiving imaging tests such as X-rays and CT scans in hospital settings as these use very low radiation dosage levels.

Radioactive sickness may seem frighteningly remote to many people, yet it remains uncommon. Radioactivity sickness levels peaked after WWII, when nuclear bombs were dropped on Nagasaki and Hiroshima, respectively. Since then, however, large-scale nuclear accidents like Chornobyl have outshone any increases in radiation sickness rates. Today, it is almost impossible for exposure to become harmful without direct physical contact with seriously radioactive substances.
