Nuclear Pharmacy

The starting point

Nuclear pharmacy quality combines pharmaceutical control with radiation protection.

Nuclear pharmacy is the specialized practice associated with radiopharmaceuticals — medicinal products that contain radionuclides and are used for diagnostic or therapeutic purposes. Depending on the organization and its licenses, work may include receiving radioactive material, preparing or compounding radiopharmaceuticals, radiolabeling, quality control, dispensing, transport staging and managing radioactive waste. PET drug manufacturing and medical-use dose preparation are not legally or technically identical activities.

The defining challenge is that microbial contamination, ordinary particles and residues, radiation exposure, and radioactive contamination are different risks. A cleanroom can reduce airborne particles while failing to detect removable radioactive contamination; a low radiation reading does not establish that an exposed sterile preparation remains microbiologically acceptable.

Critical distinction: “sterile,” “ISO Class 5,” “disinfected” and “radiologically cleared” mean different things. None of these terms proves the others.

Different radiopharmaceutical operations

Do not apply one cleanroom configuration to every nuclear pharmacy process.

No universal ISO Class 5 or ISO Class 7 statement can cover all of these settings. Classification, aseptic conditions and containment must be mapped to the actual manipulation and currently applicable chapter, license, manufacturer instructions and facility plan.

2026 regulatory reference

USP <825> is central — but it is not the only governing source.

As of this review, the January 1, 2024 version of USP General Chapter <825> is the operative published basis identified by USP. USP subsequently published proposed changes for comment, including changes discussed in 2026; a proposal should not be treated as an effective requirement. Always confirm the current official chapter through USP and the requirements adopted or enforced in your jurisdiction. USP radiopharmaceutical chapter.

Why the regulatory distinction matters: FDA states that radiopharmaceuticals are excluded from the usual FD&C Act Section 503A compounding exemptions. Its specific radiopharmaceutical guidance explains policies for certain state-licensed nuclear pharmacies and other covered facilities. Facilities should determine their own legal and regulatory framework, not borrow a rule meant for ordinary sterile compounding. FDA radiopharmaceutical guidance.

Also see the SOSCleanroom USP <797> sterile-compounding guide and USP <800> hazardous-drug guide for their separate scopes.

Engineering and zoning

A shielded workstation is not automatically an aseptic primary engineering control.

Radiopharmacy design often has to reconcile air cleanliness, aseptic technique, radioactive-material containment, operator access and shielding. A hot cell, shielded enclosure or isolator can serve different roles, but radiation shielding alone does not prove the critical air quality needed for an aseptic operation. Conversely, a clean air device does not replace a licensed radiation-protection or containment system.

How to evaluate a room or engineering control

• Classification and recovery: determine the air cleanliness level required during the specific process, including operation with personnel and equipment in place.
• Airflow and access: assess how shielding, doors, lead-glass viewing panels and manipulators affect airflow patterns and cleaning access.
• Surfaces: choose compatible, cleanable materials and maintain documented methods for difficult-to-reach corners and critical interfaces.
• Transfer points: establish outer-packaging removal, wipe-down, dedicated tools and clean-to-dirty boundaries without violating radiation-containment rules.
• Maintenance: define safe entry, coordination with the Radiation Safety Officer (RSO), monitoring, documentation and conditions for return to service.

ISO 14644-5:2025 describes operational control programs for cleanrooms, including personnel, cleaning, maintenance and material transfers. It is not a substitute for the nuclear pharmacy chapter or NRC/Agreement State requirements. ISO 14644-5:2025 overview.

The critical technical distinction

Cleaning, microbial disinfection and radioactive decontamination are different processes.

Use the correct acceptance criterion: a clean-looking surface may still contain radionuclides or viable organisms. Similarly, a negative microbial environmental sample cannot be substituted for a radiation survey. Investigation and restart decisions should be governed by separate quality and RSO criteria.

Practical contamination control

Design a controlled, compatible cleaning and disinfection program.

In nuclear pharmacy, an effective cleaning program has to account for restricted spaces, difficult shielded-enclosure geometry, time pressure, potentially contaminated waste, material compatibility and aseptic critical sites. The objective is not to use the strongest chemical available, but to apply the correct agent, technique and verification in the appropriate zone.

Sterile 70% IPA: useful, but not a universal solution

Sterile 70% isopropyl alcohol is often considered for compatible controlled-environment tasks because sterile supply, dispensing format and traceability can be important. However, sterile IPA does not replace a required cleaning step, has no inherent sporicidal claim, and is not proof of radioactive decontamination. Review the product label, SDS, flammability controls, material compatibility, and required drying instructions. Where legally required for a disinfectant claim, use an appropriately registered and labeled product.

The U.S. EPA advises that the disinfectant surface must remain visibly wet for its labeled contact time, and the method of application must match the product label. EPA disinfectant directions.

Handling wet consumables and process residue

Pre-wetted wipes can reduce manual solvent-dosing variability, but their solvent, concentration, package configuration and material must be appropriate for the task. Residual solution near instruments, radiation detectors, lead shielding, seals or electrical equipment may require special review. Any wiper or swab that contacts radioactive material must enter the approved survey, segregation and waste pathway; do not treat the product as ordinary trash based only on its cleanroom packaging.

Radiation protection and contamination

ALARA belongs to the radiation-safety program, not to a wiper data sheet.

NRC regulations and applicable Agreement State license conditions govern radioactive-material protection. ALARA means maintaining exposures as low as reasonably achievable using appropriate controls, which can include limiting time near radioactive sources, increasing distance, shielding, safe containment, work planning and relevant monitoring. These controls are selected by trained personnel and the licensed radiation-safety program.

Appropriate surveys and monitoring are described in the NRC medical-licensee guidance. A contamination survey should not be replaced by visual inspection, an alcohol wipe, or airborne particle counting. NRC medical-use FAQ: surveys.

Waste reminder: used gloves, swabs, pads, wipes, packaging, absorbents and other items may become radioactive waste if contaminated. They must be assessed, labeled, segregated and disposed of under the applicable license and RSO-approved waste procedures. SOScleanroom consumables are not substitutes for calibrated radiation instrumentation or licensed waste services.

Choose supplies by task

Match sterile status, shedding, absorbency and material compatibility to the procedure.

What information should purchasing request?

• Product identification: manufacturer SKU, exact dimensions, substrate, packaging units and suitability limits.
• Quality evidence: available technical data, sterility statements, lot/expiry traceability and any relevant certificates for that precise item.
• Chemical compatibility: SDS, proposed surface and equipment materials, and restrictions related to the required solvent or disinfectant.
• Change control: whether substitutions require pharmacist/QA review; product naming similarity does not establish equivalence.
• Supply continuity: staged quantities, sterile-package integrity and replenishment planning for shifts, outages and seasonal volume changes.

Verified SOScleanroom examples

Individual product listings to evaluate against your approved bill of materials.

The listings below were checked on the SOScleanroom website. They are selection candidates, not representations of product approval for a licensed nuclear-pharmacy procedure. Verify sterile status, pack size, current availability, manufacturer specifications and intended use before procurement.

Explore broader catalog families: sterile cleanroom wipers, precision swabs, cleanroom gloves and apparel, cleaning and disinfection solutions and cleanroom mop systems. Product pages may change and some items have clearance or special-order status; check availability rather than assuming immediate inventory.

Different evidence, different purposes

Environmental monitoring is not radiation surveying, and neither alone releases a drug product.

Keep the monitoring systems linked through deviation control, but do not collapse different measurements into a single “clean” indicator. A cleanroom certificate does not certify every surface or aseptic manipulation; a radionuclide decay period does not establish sterility.

Audit-ready quality records

Build documentation that explains what was done, by whom and under which authority.

• Authority and scope: licenses, applicable USP chapter editions, policies, authorization to perform the task and responsibility of the pharmacist, RSO and quality unit.
• People and technique: required training, aseptic qualification where applicable, glove and garment technique, periodic evaluation and retraining.
• Engineering controls: certification and service history for qualified aseptic devices, equipment condition, maintenance interventions and return-to-service approvals.
• Cleaning and disinfection: written zone-specific methods, materials, activity restrictions, frequencies, label instructions and completion records.
• Radiological controls: approved survey procedures and instruments, required monitoring records, spill/decontamination documentation and waste traceability.
• Product records: lot and expiry, preparation or repackaging record when applicable, quality checks, packaging/labeling, disposition and deviations.
• Supplies: item-level lot documentation as available, current specifications, authorized substitutes and evidence of change-control decisions.
• Investigations: trend review, deviations, excursion impact assessments, corrective/preventive actions and documented release decisions.

Supplier documentation assists audit readiness, but a technical data sheet or certificate for a wiper does not establish that a radiopharmaceutical batch, operation or room complies with USP <825> or NRC license conditions.

Suggested site-readiness checklist

An educational self-assessment for nuclear pharmacy managers and technical purchasers.

Use this framework as a discussion aid, not as a compliance certificate. The facility must translate it into controlled procedures, instrument-specific requirements, acceptance limits and sign-offs applicable to its authorized work.

Troubleshooting and event response

Common early warning signs and the appropriate first investigation.

Suggested SOP library

Procedure modules worth maintaining as separate controlled documents.

For staff training, cross-reference SOSCleanroom Training Materials & How-To Guides, Critical Cleaning and our Technical Vault. These educational resources support preparation of local procedures but do not replace validated instructions or professional supervision.

Authority beyond the catalog

Important nuclear pharmacy capabilities that are not ordinary consumables.

A reliable radiopharmaceutical program may require capabilities beyond anything in a cleanroom distributor catalog: shielding design, ventilation and hot-cell engineering, calibrated dose calibrators and radiation instruments, radiopharmaceutical quality testing, PET drug manufacturing expertise, aseptic-process qualification, HEPA certification, medical physics advice and licensed radioactive-waste disposal. These are specialized disciplines.

SOScleanroom can support the consumable side with candidate sterile wipers, swabs, cleaning solutions, gloves, apparel, contamination-control accessories, manufacturer documentation and purchasing support. The site does not replace your licensed nuclear pharmacist, RSO, Qualified Person or quality unit, accredited test laboratory, engineering specialist, or regulator.
