Radionuclide Drug Conjugate (RDC) segmentation by type dissects the market into alpha, beta, and gamma emitters, each dictating distinct capital expenditure and regulatory pathways. Alpha conjugates (e.g., ²²⁵Ac, ²¹³Bi) command premium pricing—up to 40 % higher COGS—because cyclotron or reactor production yields are sub-gram and require complex daughter-isotope harvesting; nevertheless, their high linear-energy transfer drives 60 % of ongoing Phase II/III pipelines in prostate and neuroendocrine indications, anchoring the segment’s >30 % share of forecast market value. Beta emitters (e.g., ¹⁷⁷Lu, ⁹⁰Y) deliver mid-tier revenue contribution, balancing manageable DOTA chelation chemistry against scalable reactor supply; this segment is forecast to expand fastest (CAGR 18 %) as CDMOs add ¹⁷⁷Lu capacity. Gamma conjugates, primarily diagnostic, generate lower per-dose revenue but are indispensable for companion imaging, creating pull-through demand that underpins the full RDC value chain.
