Characteristics

 Matter decay radiation Process Formula Alpha radiation Ur --> TH + Alpha radiation Radiation at speed less thanh speed of visible light $v=\gamma ={\sqrt {1-{\frac {v^{2}}{C^{2}}}}}$ $M=m_{o}(\gamma -1)$ $p=M\gamma$ $E=p\gamma$ Beta radiation C --> N + Beta radiation Radiation at speed less thanh speed of visible light $v=\omega _{o}={\sqrt {\frac {1}{\mu _{o}\epsilon _{o}}}}=C=\lambda _{o}f_{o}$ $E=pv=pC=p\lambda _{o}f_{o}=hf_{o}$ $h=p\lambda _{o}$ $p={\frac {h}{\lambda _{o}}}$ $\lambda _{o}={\frac {h}{p}}$ Gamma radiation Radiation at speed less thanh speed of visible light $v=\omega ={\sqrt {\frac {1}{\mu \epsilon }}}=C=\lambda f$ $E=pv=pC=p\lambda f=hf$ $h=p\lambda$ $p={\frac {h}{\lambda }}$ $\lambda ={\frac {h}{p}}$ Deflected when enter magnetic field Penetration capability
