Dose equivalent (Sv)

Layer 1 — Physicsin the radiation-physics subtree

H = Σ wR × D with radiation weighting factor wR (1 for β/γ, 20 for α). Linked to stochastic health risk. ICRP recommendations (1 mSv/y public, 20 mSv/y occupational).

Radiation quality factor Q(L)
H = w_R · D: w_R(photon)=1, w_R(α)=20, w_R(neutron)=f(E)
w_R(α) = 20: 1 Gy α absorbed ⇒ 20 Sv equivalent
