Understanding Low Specific Activity - LSA - Material [Energy]: Definitions and Classifications

Definition & Meaning

Low Specific Activity (LSA) material refers to certain types of radioactive materials that have limited specific activity. These materials are classified as nonfissile or are exempt under specific regulations. LSA materials are categorized into three groups based on their characteristics and activity levels. The shielding materials surrounding the LSA do not count towards the average specific activity calculations of the package contents.

Real-world examples

Here are a couple of examples of abatement:

  • Example 1: A company transporting uranium ore that falls under the LSA-I category must adhere to specific packaging and transportation guidelines to ensure safety.
  • Example 2: A research facility handling water with tritium concentration (LSA-II) must monitor and report its activity levels to comply with regulatory standards.

Comparison with related terms

Term Definition Difference
Low Specific Activity (LSA) Radioactive materials with limited specific activity. Focused on nonfissile materials and specific activity thresholds.
High Specific Activity (HSA) Radioactive materials with higher levels of specific activity. HSA materials are subject to stricter regulations due to their potential hazards.
Exempt Material Materials that are not subject to regulatory control due to low activity levels. Exempt materials have even lower thresholds than LSA materials.

What to do if this term applies to you

If you are involved with LSA materials, ensure that you understand the relevant regulations and classifications. It may be beneficial to consult legal resources or templates from US Legal Forms to assist with compliance. If your situation is complex, consider seeking professional legal advice to navigate the regulatory landscape effectively.

Quick facts

  • Typical classifications: LSA-I, LSA-II, LSA-III.
  • Average specific activity limits vary by group.
  • Regulated under Title 10 CFR Part 71.
