Discover of matter decay radiation

Marie curie discovered Uramium decay into Thorium generate Alpha radiation

Ur --> Th + phóng xạ alpha

Henry Beckelrel discovered Carbon decay into Nitrogen generates Beta radiation

C --> N + phóng xạ beta

Characteristics

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