A sealed source refers to any byproduct material that emits radiation and is securely encased in a protective capsule. This design is specifically intended to prevent any leakage or escape of the radioactive material. Sealed sources are commonly used in various applications, including medical treatments and industrial processes, where controlled radiation is necessary.
Sealed sources are primarily regulated by the Nuclear Regulatory Commission (NRC) under Title 10 of the Code of Federal Regulations (CFR), particularly in Part 35, which pertains to the medical use of byproduct material. Legal contexts for sealed sources include:
Users may manage compliance with regulations through legal forms and templates provided by services like US Legal Forms.
Here are a couple of examples of abatement:
Example 1: A hospital uses a sealed source containing iodine-125 for treating thyroid cancer. The iodine is securely contained, minimizing the risk of radiation exposure to patients and staff.
Example 2: An industrial company employs a sealed source for non-destructive testing of welds in pipelines to ensure structural integrity (hypothetical example).
The primary regulation governing sealed sources is found in:
| State | Regulatory Body | Key Differences |
|---|---|---|
| California | California Department of Public Health | Additional state-specific licensing requirements for sealed sources. |
| Texas | Texas Commission on Environmental Quality | More stringent disposal regulations for sealed sources. |
This is not a complete list. State laws vary, and users should consult local rules for specific guidance.
| Term | Definition | Key Differences |
|---|---|---|
| Unsealed Source | Radioactive material that is not contained in a capsule. | Unsealed sources pose a higher risk of radiation exposure compared to sealed sources. |
| Radioactive Waste | Material that is radioactive and no longer useful. | Sealed sources are designed for use, while radioactive waste is typically disposed of. |
