Radioactive decay produces three flavors of emissions: alpha, beta, and gamma. Alpha particles comprise 2 neutrons and 2 protons. Because of their large mass and relatively slow speed, alpha particles ...

To understand nuclear decay equations. How to measure the activity of radioactive sources. Spontaneously means that the process of radioactive decay can not be speeded up or slowed down by physical ...

The nuclei of certain atoms are stable and under ordinary circumstances, stable nuclei do not undergo change. The nuclei of other atoms are unstable. These nuclei undergo change spontaneously, that is ...

FECYT – Spanish Foundation for Science and Technology: A team of researchers from the University of Zaragoza (UNIZAR) and the Institut d’Astrophysique Spatiale (IAS, in France) has developed a ...

Alpha particles comprise 2 neutrons and 2 protons. Because of their large mass and relatively slow speed, alpha particles are the least penetrating of the three types of radiation, and can be stopped ...
