Since 241 is a prime, sqrt(241) cannot be simplified.
241% means 241/100 = 241/100 ===========simplest form about 2 and 2/5 ==========mixed number
241 is a prime number, so the prime factorization is just 241.
841
241 × 7 = 1687
Americium-241 being radioactive - emit alpha particles - is used as a source to ionization of air.
The term "used" is not adequate. The radioactive decay of Am-241 is associated with the emission of alpha particles and gamma rays.

Americium - atomic number 95
The fire alarm device is usually equipped with an Amercium-241 that is alpha emitter source together with a battery derived electric circuit. In the normal situation the alpha particles ionize the air causing circuit connection. However when there is a smoke the circuit is disconnected due to the smoke that acts as an insulator and hence the alarm is actuated.
Americium 241
Alpha radiation is emitted from the amercium button in a smoke detector. When smoke goes into the smoke detector it blocks the stream of alpha particles emitted from the americium. That triggers an alarm.
AMERICIUM 241!
Since 241 is a prime, sqrt(241) cannot be simplified.
1 x 241, 241 x 1.
30% of 241 = 241*30/100 = 72.3
If used inappropriately or carelessly, Americum-241 can be hazardous. It is a radioactive material that decays by emission of an alpha particle. Alpha particles are only dangerous if they are emitted by atoms within your body, so Americium-241 is only hazardous if it gets into your body. Americium-241 is used in ionization-type smoke detectors. In that use it is not hazardous unless the smoke detector is severely abused.
