Weight-scaled pediatric administered activity with a minimum-activity floor
High-yield mode — key points, high-yield facts, tables & quizzes only. Toggle off for full text.
Enter the adult reference activity, the child's weight, and a minimum-activity floor to estimate a weight-scaled pediatric administered activity. This is a conservative linear convention — the EANM Dosage Card and North American consensus use non-linear, class-based multipliers, so use your local card for the definitive value (see Pediatric Nuclear Medicine & Dosing).
Pediatric weight-based activity (with minimum)
kg
Recommended = weight × per-kg activity, floored at the minimum and capped near the adult activity (North American Consensus / EANM paediatric dosage-card values, MBq). Never scale below the minimum — too little activity gives a non-diagnostic study and a repeat. Confirm against the current dose card.

INFLinear weight scaling is a conservative convention — class-based schemes (EANM card) are non-linear; use local protocol for the definitive activity.
