a. Americium-241
Smoke detectors might have an ionizing chamber. If it does, the chamber holds a radioactive nuclide to ionize the particles in the smoke to set off the detector. Usually the radioactive source is americium.

What are the benefits and dangers of radioactivity?
- Radioactive substances are often used as tracers in medical investigations - They can also be used to treat some conditions such as cancer - Medical diagnostic - Isotopic sources of energy - Tracers in hydrology, biology, agriculture, etc. - Minerals dating in geology - Tracers in chemical industry - Tracers to study damage of metals, building materials, etc. - Radiochemical polymerization - Sterilization of foods, medical equipment, wastes - Smoke detectors - Water detectors and many others important applications. But uncontrolled use of radioactivity may be dangerous; internal contamination or external irradiation must be avoided.
Does barometers contain Mercury?
Many do, but not all. Most barometers that people would have in their homes are aneroid barometers, which don't contain any mercury.
Electrolytes are able to conduct electricity because they contain many..?
The answer is "ions"
What does significance of the study contain?
The significance of studies contain a great many different things. This significance includes being more educated and being able to change things.

What the radioactive element is used in smoke detectors?
It's usually americium-241. It undergoes alpha-decay with a half-life of about 400 years. Am-241 is artificially manufactured; it doesn't occur in nature.
Using BRK Smoke Detectors to Protect Your Investments?
BRK Smoke Detectors have long been recognized as one of the top brands when it comes to smoke detectors and many other types of gas detectors. Because of their tried and tested construction, BRK smoke detectors are able to stand up to years of abuse without having to undergo a whole lot of maintenance to stay in working order. This is why many companies tend to use BRK smoke detectors when they need to cover a large area of industrial use with a smoke detector that is guaranteed to provide years of carefree service. If BRK smoke detectors are trusted for this, they can be trusted for anything.
What kind of nuclear decay occurs within most smoke detectors?
Many smoke detectors use Americium-241, which emits alpha rays, to keep air ionized.
How many smoke detectors are needed in a house?
Ideally, a smoke detector for every room should be in place.
Where would I go about purchasing interlinked smoke detectors for a good price?
Try checking www.safelincs.co.uk/. They have a wide variety of radio interlinked smoke detectors with many add on options available. To get a competitive price you can always compare prices on www.amazon.com.
What are some things made popular by nasa that are useful everyday?
There are many but here are a few, smoke detectors.
How many smoke detectors should be installed in a 100 square meter room?
One, in the center of the ceiling of the room.
How many types of smoke alarms can you get?
There are many types of smoke DETECTORS and self-contained smoke ALARMS. Some smoke detectors use ionizing radiation; others use photo-electric sensors. More sophisticated sensors use chemical reactions to detect specific types of smoke or to measure specific chemical composition and concentration of smoke. Photo-electric sensors are said to be more sensitive to smoldering fires (large particles) than ionizing detectors, meaning you may get an earlier warning from photo-electric.
How to Keep Your Smoke and Fire Detectors Working Perfectly?
When you invest in smoke and fire detectors, you're doing it to help enhance the safety and security of your home. However, many people start to forget that these detectors need to be maintained like any other piece of equipment in their homes and the smoke and fire detectors start to degrade. In order to keep your smoke and fire detectors working in tip-top shape, make sure to regularly test them using the integrated test button. Also, don't just wait until the "low battery" beeps start going off to change the batteries. Change batteries regularly whether or not they're low.
How many type of smoke detectors?
There are basically two types of smoke detector; one type measures the opacity of the air to literally "see" if there is smoke. The other type tests for ionization that occurs when there is a fire. That type smoke detector uses a small radioactive chip to determine if freshly ionized smoke is present. It's a far more accurate means of determining the presence of fire and associated hazardous smoke. Many smoke detectors use a combination of both detectors. A separate type of detector is the carbon monoxide detector, which senses the presence of harmful carbon monoxide in the air. Most will even indicate the percentage of carbon monoxide. Note that carbon monoxide is typically present when a furnace or other heating device malfunctions.
