Below, we’ve created a guide to radiopharmaceutical cleanroom design — giving you an inside look at all the design considerations that go into creating one of these controlled, cutting-edge spaces.
Of course, all radiopharmaceutical cleanroom designs are a bit different. It depends on a variety of factors, such as the particular application happening within them, the space in which they’re built, etc. However, many of them have the same basic components and design considerations. We’ve listed six fairly common ones below:
The main component of any cleanroom is its ISO classification, and radiopharmaceutical cleanrooms are no different. In most cases, radiopharmaceutical cleanrooms are required to meet ISO Class 7-8 standards. However, they may also have designated areas or chambers that must meet even more stringent standards, like ISO Class 6 or higher.
In order to meet high levels of cleanliness and environmental control, radiopharmaceutical cleanrooms are most often built as HardWall structures. This type of cleanroom has the most control over contamination, temperature, humidity, pressure, and static.
Cleanroom size can greatly vary from one radiopharmaceutical cleanroom project to another. But in terms of effective radiopharmaceutical cleanroom design, the most important thing to consider is allowing enough space for all necessary equipment, as well as personnel and product flow.
Radiopharmaceutical cleanrooms generally host multiple pieces of equipment, the most common being hot cells. Hot cells are shielded containment and operating chambers that protect cleanroom personnel from radioactive substances within the medicines.
They’re usually around 4 feet wide and 12 feet tall, so allocating space for a few of them can be challenging — especially when you also need to accommodate space for efficient workflow surrounding them. That’s where a radiopharmaceutical cleanroom designer’s expertise really comes in handy.
Radiopharmaceutical cleanroom design can also get a bit complicated when it comes to pressurization and confirming there is a cascading effect; where the most stringent or highest classification cleanroom should have the highest positive pressure. When a facility has multiple cleanroom areas (which is typical in radiopharmaceutical applications), it’s critical to design pressure and air to flow a certain way so that particles and contaminants are unable to enter the most controlled space in the facility.
In addition, radiopharmaceutical cleanrooms typically have fume hoods that are operating at ISO 5 and need to be exhausted to the exterior or out of the cleanroom suite.
In radiopharmaceutical cleanrooms, temperature and humidity are both important factors to keep under strict control and monitoring. Radiopharmaceuticals cannot be kept under extreme temperatures or humidity levels, otherwise they will become less effective, run the risk of microbial growth, or be unsafe for human consumption. Therefore, environmental control and monitoring systems are built into many radiopharmaceutical cleanrooms’ designs.
Finally, radiopharmaceutical cleanroom operations call for a variety of unique pieces of equipment and technology. These devices could include (but aren’t limited to) some of the following:
