## 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 ${\displaystyle v=\omega ={\sqrt {\frac {1}{\mu \epsilon }}}=C=\lambda f}$  ${\displaystyle E=pv=pC=p\lambda f=hf}$  ${\displaystyle h=p\lambda }$  ${\displaystyle p={\frac {h}{\lambda }}}$  ${\displaystyle \lambda ={\frac {h}{p}}}$
