Radioactive Smoke Detectors Can Be More Dangerous Than Fire

There are two main types of smoke detectors that are sold to the public: ionizing and photoelectric. They detect fire in differing ways. Both of the technologies are widely misunderstood, to the degree of there being rampant, ludicrous explanations abounding on the Internet from people who are simply not trained in electronics. The so-called “ionizing” smoke alarms utilize a radioactive material, americium-241, which is placed inside of what is referred to as an ionization chamber. This metallic chamber features a slight gap between its energized plates and the radioactive americium. This design produces what is essentially an internal radiation detector. Whenever the americium’s radioactive emissions are warped (frequency changed) by smoke, the alarm sounds. Alternatively, the much safer photoelectric-based alarms utilize light instead of gamma radiation, wherein a beam of light is aimed to miss the sensor during normal operation. Whenever smoke is presented, the light is dispersed by it. This causes some of the light to reliably strike the sensor, sounding the alarm.

The Radiation Danger

A variety of watchdog groups have warned about the danger of having radioactive americium-241 inside homes, but they strangely retracted their warnings without explanations. Ralph Nader is one such example. He issued a warning in 1976.

There are no trustworthy sources for determining how severe the risk of americium exposure is, because all of the research has been done by the same nuclear industry that has sought innovative ways to dispose of its nuclear waste products, such as americium. The defenders of americium’s use often state that the amount of radiation released is little different from that of the background radiation within a busy city. These proponents of child radiation exposure intentionally fail to mention the differences between electromagnetic radiation and nuclear radiation, for nuclear radiation (such as that which is produced by americium) is exceedingly more dangerous. Nevertheless, both types of radiation cause a variety of health issues, including cancers; especially the gamma radiation from nuclear waste. Despite the alleged “harmless” nature of the radioactive smoke detectors, customers are urged not to dispose of them as household garbage. Instead, American citizens are asked to return their old smoke detectors to manufacturers or to the Nuclear Regulatory Commission (NRC). Furthermore, according to F.E.M.A., the radioactive smoke detectors are an occupational hazard inside warehouses which store them. How is that for doublespeak? It’s like they are saying that we should put the radioactive product inside our houses, but not into the community dump, since their families might get environmentally exposed too. If americium radiation exposure were indeed safer than our background radiation exposure, then it would mean that this unnatural substance emits a safe and health-generating form of radiation, which somehow protects us from the less wonderful radiation. These “facts” are part of the nuclear-industry’s “science”.

“When more than 100 detectors are to be stored, they should be located in areas not normally occupied by personnel… Where more than 200 detectors are stored in the same room, radiation monitoring devices should be used to check the radiation levels in the area.”

Within their public document, the U.S. Federal Emergency Management Administration omitted the part about employees needing to wear lead suits for protection. Funny how those mistakes happen. The case of americium is very similar to that of fluoride. It is another hazardous, industrial waste byproduct from the nuclear industry, for which the industry would have had to otherwise pay exorbitant fees to dispose of, if it had not found a way to make us feel that it is essential for our safety. Americium is entirely an “artificial element”, which means that it never exists naturally. The nuclear industry found that it could actually sell it to us, for a profit, as something that we are supposed to believe is needed for our health and safety.

Greater Fire Dangers

The two main types of smoke alarms have major differences in reliability. In “fast flame” fires, like those which are accelerated by petrochemicals, such as gasoline; the radioactive smoke detectors detected fires about 30 to 90 seconds faster than the photoelectric type. However, in slow-burning, smoldering fires, which comprise the vast majority of home and office fires, the photoelectric smoke alarms detected smoke 15-18 minutes sooner than the radioactive sensors. Moreover, the “ionizing” smoke detectors outright failed to function 20 percent of the time, according to studies.

Despite the shoddy results for the ionizing (radioactive) smoke detectors, which illustrate the prudence of exclusively using photoelectric smoke alarms, 95% of American homes with smoke detectors use the inferior, radioactive type. For this 95%, a large portion of them will die from undetected fires, but a much larger portion of them will be said to die from the (radiation-induced) cancers, even though it will be the radioactive cancer treatments that end most of them. Absolutely no-one from government, the nuclear industry, or the medical industry will be held accountable.
