S+T Perspectives: Five Keys to Future-Ready Radiopharmaceutical Facility Design

Once confined primarily to diagnostic imaging, radiopharmaceuticals are rapidly expanding into therapeutic use, fundamentally reshaping how these programs are developed and delivered. As therapeutic pipelines mature, higher activity levels and tighter integration across R&D, manufacturing, and clinical supply are becoming standard.

When the facilities that produce radiopharmaceuticals fail to evolve at the same pace, they can quickly shift from being enablers of innovation to operational bottlenecks, creating real implications for facility planning and design. Based on Hixson’s experience working in this sector, the physical environment must support extremely time-sensitive production, specialized equipment, regulatory requirements, and future growth, all while prioritizing safety and operational efficiency. Therefore, when designing a radiopharmaceutical facility, five key factors must be considered:

1. Site selection and supply chain proximity are among the most critical decisions. Many radiopharmaceutical products have extremely short half-lives…sometimes as little as 30 minutes…requiring doses to be produced, packaged, transported, and administered in tightly controlled time windows. This makes proximity to end users essential, whether that means locating near major hospital systems, within dense healthcare networks, or close to reliable transportation hubs such as airports. The goal is a dependable, condensed supply chain that moves material efficiently from isotope production to patient delivery with minimal delay.
2. Inside the facility, workflow efficiency and adjacency planning become paramount. The internal layout must support smooth, direct material flow from cyclotron or isotope delivery to synthesis, quality control, dispensing, and outbound distribution. Unnecessary backtracking or complex circulation paths can introduce risk and reduce efficiency. At the same time, additional layers of protection must be integrated throughout the space, including appropriate shielding, controlled adjacencies, and clearly defined radiation safety zones to protect personnel while maintaining operational speed.
3. Facilities that include cyclotron infrastructure face especially demanding design requirements. Cyclotrons require heavily shielded concrete vaults with thick walls and substantial slab foundations to address both radiation protection and vibration isolation. These machines impose significant structural loads, and their supporting systems, such as chilled water, backup power, and specialized mechanical and electrical infrastructure, must be carefully coordinated early in design. In addition, planning for future access, whether for maintenance, replacement, or additional cyclotron installations, is another crucial consideration.
4. Facility flexibility and expansion is also important, given the rapid pace of growth in the radiopharmaceutical industry. If building a new facility, that space must not only meet today’s needs, but should remain adaptable for future therapies, increased throughput, or dual diagnostic/therapeutic operations. Repurposing spaces not originally designed for radioactive materials is possible, but it often introduces added challenges. These may include workflow planning, shielding requirements, equipment access, and cleanroom integration, particularly when ISO-classified environments must be introduced into non-lab structures.
5. Finally, support infrastructure and safety systems must be fully integrated. This includes radioactive waste management areas that allow material to decay safely before removal, personnel monitoring systems, shielded workstations, and reliable mechanical and electrical systems to support uninterrupted operations. While many of these elements are familiar in laboratory design, the combination of radiation safety, time sensitivity, and regulatory oversight makes early coordination especially important.

As radiopharmaceuticals continue to evolve from a niche diagnostic tool into a cornerstone of precision medicine, the facilities that support them must evolve as well. Thoughtful site selection, efficient layouts, specialized infrastructure, and future-ready design are no longer optional: They are foundational to success in this rapidly expanding field.
