EANM 2016 Pediatric Dosage Standardization
Power-law behind the EANM table values:
\(\displaystyle A = A_{\text{baseline}} \times \left(\frac{w}{3}\right)^{\!\alpha}\)
Calculation uses the tabulated multiples directly.
Exponent α by class (derived from EANM table):
If calculated value < minimum recommended — use minimum.
