Curium-242 is not suitable for use in smoke detectors because it is a radioactive isotope that emits high-energy alpha particles, which can be harmful to human health if exposed in close proximity over extended periods of time. Additionally, curium-242 has a long half-life, making it unsuitable for the short-term detection requirements of smoke detectors.
Curium-242 has 122 neutrons and Curium-244 has 124 neutrons. This neutron difference causes them to have different decay pathways and half-lives, with Curium-242 having a shorter half-life than Curium-244.
The first nuclear reaction to obtain curium was:Pu-239 + He-4 = Cm-242 + nNow curium is separated from burned nuclear fuels.
The first time curium was obtained by the reaction:Pu-239 + He-4 = Cm-242 + nNow curium is obtained from burned nuclear fuels.
The first nuclear reaction to obtain curium was:Pu-239 + He-4 = Cm-242 + nNow curium is separated from burned nuclear fuels.
The specific activity of the isotope curium-242 is 3 400 Ci/g.
The other product formed when curium-242 is bombarded with an alpha particle is uranium-238.
The nuclear reaction used to prepare curium was:Pu-239 + He-4---------------Cm-242 + n
The first nuclear reaction to obtain curium was:Pu-239 + He-4 = Cm-242 + nNow curium is separated from burned nuclear fuels.
The nuclear reaction is: 242Cm + 4He = 245Cf + n
The nuclear reaction is: 242Cm + 4He = 245Cf + n
The nuclear reaction is: 242Cm + 4He = 245Cf + n
