Sources of radiation include
There are dozens of alpha particle sources, but some common ones are:
3H (Tritium - used in fusion reactors and watches)
238U (once used to colour green glassware)
241Am (used in smoke detectors)
252Cf (used in moisture gauges)
238Pu (used to power spacecraft)
239Pu (used in nuclear weapons and power stations)
210Po (once used to poison Alexander Litvinenko)
226Ra (creates a laboratory neutron source when mixed with Be)
222Rn (radon gas - a health hazard in many localities)
210Th (used in coloured glazes)
229Th (used in fluorescent lights)
232Th (used in magnesium alloys for aircraft engines)
The varied applications reflect the different half-lives, availability, cost and chemical or biochemical properties of the different elements.
Well some good sources are cell phones, microwave ovens, television, computers, digital clocks and some radios.
Radiation sources are stored in containers which provide shielding to make handling and transport of the sources safe. The amount of shielding depends on the type of radiation-a gamma source requires more than a alpha or beta emitter.
A zinc sulfide scintillator probe is used to detect alpha radiation. The scintillator probe is just sensitive to alpha radiation.

Gamma radiation is the strongest, followed by beta, followed by alpha. So, in answer to your question; alpha is the weakest type of radiation :)
Radioactive sources release some form of radiation, in the case of smoke detectors the specific type will be alpha radiation- most likely from americium 241. The alpha radiation is a helium nucleus which is highly ionizing but is fairly safe since it can only travel around about 5cm in the air, the act of a stream of alpha radiation being intercepted by CO2 cuts a circuit and is how the CO2 is detected.

Yes, alpha radiation is an ionizing radiation.
Mostly inhalation/ingestion of alpha emitter dust particles. These offer little protection from other types of radiation sources.
Yes, alpha radiation is an ionizing radiation.
Alpha (and beta) radiation is "particle radiation" Gamma is electro-magnetic radiation.
No. Decay is the process, radiation is the product.

Alpha and Beta Radiation are types of ionizing radiation. They are both charged particles though Alpha is heavier than the particle Beta.
It can be used for smoke detectors
