  1. beta radiation is divided into: Beta- and Beta+ radiations
  2.  
  3. Beta- radiation causes an atom to lose one neutron and gain one proton.
  4. Hence, the atomic number is increased by 1 and (liczba masowa) is not changed.
  5.  
  6. Beta+ radiation causes an atom to lose one proton and gain one neutron.
  7. Hence, the atomic number is decreased by 1 and (liczba masowa) is unchanged.
  8.  
  9. But, we can also take at a scope only single neutron or proton; not necessarily the whole atom. So:
  10.  
  11. Beta- radiation when in contact with isolated neutron causes it to transform into proton.
  12.  
  13. Beta+ radiation when in contact with isolated proton causes it to (surprise surprise) take no effect. Why?
  14. Because mass of neutron is slightly higher (slightly w chuj, praktycznie identyczne).
  15. So transition proton --> neutron is not possible, because mass cannot be increased without additional energy.
  16.  
  17. In an atom-scope proton --> neutron is possible, because the energy is taken from <jakieś tam atom binding idk>
  18.  
  19. ---------
  20.  
  21. Energy released/absorbed by beta radiation is:
  22.  
  23. E = [delta masses] * c^2, where:
  24.  
  25. delta masses = Initial Atom mass - Final Atom mass - electron mass - neutrino(antineutrino) mass
  26. c = speed of light
  27.  
  28. ---------
  29.  
  30. Beta radiation is directly related to half-life of an atom. (? chyba)
