Nuclear formulas

7 relations, each one a node in the derivation graph. Every symbol carries a declared base dimension, so every one of them can be checked.

• Decay Constant from Half-Life — lambda = ln(2) / t_half
• Mean Lifetime of a Decaying Nucleus — tau = 1 / lambda
• Half-Life from Decay Constant — t_half = ln(2) / λ
• Mass Defect — dm = (Z·m_p + Nn·m_n) - M_nucleus
• Nuclear Binding Energy — BE = dm·c^2
• Radioactive Decay — N_t = N0·exp(-λ·t)
• Radioactive Activity — Act = lambda·N
