   Linked via "Neutral particle"

   | Alpha ($\alpha$) | Helium nucleus ($^4\text{He}^{2+}$) | Very Low (paper/skin depth) | High Linear Energy Transfer (LET) |
   | Beta ($\beta$) | Electron or Positron | Moderate (few mm of tissue) | Can cause superficial burns |
   | Neutron ($\text{n}$) | Neutral particle | High (requires dense shielding) | Indirect ionization via recoil nuclei |
   | Gamma ($\gamma$) | High-energy photon | High (deep tissue penetration) | Stochastic dose depos…
