They were basically designed to help people up in the first space American space station (skylab) detect toxic smokes and gases up in space. Since you can't really run anywhere in space, you had to be alerted as soon as possible.
no it was not
A portable carbon monoxide detector is used to sniff an area in a confined space to make sure that there is no carbon monoxide gasses present before any personnel are allow to enter the confined space.
Yuri Gagarin flew aboard Vostok 1 for 108 minutes or nearly a complete orbit of the Earth, a Soviet space mission and the first man in space.

depends on your prespective
The commonest use of alpha particles is probably in smoke detectors. The americium in the smoke detectors emits alpha particles. If smoke is present, it stops the alpha particles more efficiently than air, creating ions in the detection area of the device. The ions make the air more conductive, and the conductivity is sensed by the detector, which sets of the alarm. Alpha particles are also used in the radioisotope thermoelectric generators that power pacemakers and space probes.
Smoke detectors
I don't believe that if you place a smoke detector inside a closed space like above a false ceiling , it will have the same effect than if it was attached to the ceiling on the occupied space side. See the related link for some general guidelines and always check local codes or with the fire marshall for specifics.
smoke weed and hve sex then the answer will come to you.It worked for me
Most smoke detectors work either by optical detection (photoelectric) or by physical process (ionization), while others use both detection methods to increase sensitivity to smoke. For the alarm part, in many single family detached and smaller multiple family housings, a smoke alarm is often powered only by a single disposable battery. An optical detector is a light sensor. When used as a smoke detector, it includes a light source (incandescent bulb or infrared LED), a lens to collimate the light into a beam, and a photodiode or other photoelectric sensor at an angle to the beam as a light detector. In the absence of smoke, the light passes in front of the detector in a straight line. When smoke enters the optical chamber across the path of the light beam, some light is scattered by the smoke particles, directing it at the sensor and thus triggering the alarm. An ionizing detector type of detector is cheaper than the optical detector; however, it is sometimes rejected because it is more prone to false alarms than photoelectric smoke detectors. It can detect particles of smoke that are too small to be visible. It includes about 37 kBq or 1 µCi of radioactive americium 241, corresponding to about 0.3 µg of the isotope. The radiation passes through an ionization chamber, an air-filled space between two electrodes, and permits a small, constant current between the electrodes. Any smoke that enters the chamber absorbs the alpha particles, which reduces the ionization and interrupts this current, setting off the alarm. From Wikipedia.
yes,smoke does have mass and it does occupy space
The space mission was called The Apollo11.
a space mission is a journey made by a manned or unmanned vehicle into space for a specific reason.
The Government pays for the Cassini space mission.
These little handheld devices can detect the composition of gases in your home, in order to determine if there is any gas that is in excess, such as smoke. You can imagine how that would aid in home security if, for example, a fire were to break out.
The last space shuttle mission was STS-135
