The reaction is given by

[tex]\\ \rm\Rrightarrow {}^{127}_{56}Ba\longrightarrow {}^{0}_{+1}\beta+{}^{127}_{55}Cs[/tex]

Barium goes underneath beta decay to form Ceaseum

  • Cs is very mellable element
  • It can melt on your hand

[tex]\sf {}^{127}_{56}Ba\longrightarrow {}^0_{1}\beta+{}^{127}_{55}Cs[/tex]

Remember

  • Radioactive decays are first order reactions
  • The rate constant doesn't depend upon initial concentration
  • It's never ending reaction
