PARLIAMENT QUESTION: DOMESTIC SELF- SUFFICIENCY IN CRITICAL MEDICAL RADIOISOTOPE SUPPLY प्रव तथ: 12 AUG 2026 3:03PM by PIB Delhi Molybdenum-99 (Mo-99), Iodine-131(I-131) and Lutetium-177 (Lu-177) are the most important reactor- produced medical radioisotopes, accounting for nearly 90% of all Nuclear Medicine applications. Owing to their relatively short half-lives, these medical radioisotopes are produced at regular intervals, typically on a weekly or fortnightly basis in the Dhruva reactor, Bhabha Atomic Research Centre (BARC).
The total activity of 99Mo, 131I and 177Lu based radiopharmaceutical products produced and supplied during the past five years is detailed below.
Radioisotope Production Production Data (Ci) capacity (Ci) 2021- 2022-23 2023-24 2024-25 2025-26 22 Lu-177 50 Ci/batch 473 532 684 681 976 99Mo-99mTc 50 Ci/week 662 693 268 283 550 I-131 50 Ci/week 749 813 710 623 770 During maintenance shutdown of reactor/radiochemical processing facility or non-availability due to technical reasons, these radioisotopes are procured through imports from overseas producers for production and supply of radiopharmaceuticals to nuclear medicine centres.
The details of the medical radioisotopes imported during such periods, along with the quantities imported, are summarized in the Table below.

The details of supply shortfalls during the past five years are presented below:
Radioisotope Short supply/Cancellation 2021-22 2022-23 2023-24 2024-25 2025-26 Mo-99 2 1 batch 13 batches 19 batches Nil batches (52 batches/annum) I-131 1 batch Nil 4 batches 10 batches 3 batches (52 batches/annum) Lu-177 Nil 2 batches 2 batches 7 batches 3. batches (52 batches/annum) Bhabha Atomic Research Centre (BARC) a Research and Development unit under Department of Atomic Energy (DAE) has obtained administrative and financial sanction to the project “Engineering and Construction of Isotope Production Reactor”. It is expected that production is likely to start around 2035 with 0.5 MCi(million Curie) radio-isotope production capacity.
This information was given by Union Minister of State for Prime Minister’s office and Personnel, Public Grievances and Pensions, Atomic Energy and Space, Dr. Jitendra Singh, in a written reply in the Lok Sabha today.
