Indoor/Outdoor Decon Query Tools – Definitions
| Term | Definition |
|---|---|
| Decontamination Technology | The name of the chosen technology |
| Description | A general description of the chosen technology |
| Indoor Surface | The type of surface material which was tested during research |
| Testing Method | Description of method application as used during the evaluation |
| % Removal |
The percentage of the following applied radioactivity removed during the evaluation. ASFM (aqueous simulated fallout material): 2.5-mL aqueous solution of 0.8 μCi/mL Cs-137 (as cesium chloride); 2 μCi deposition using a sprayer |
| Area Decontaminated (m2/person day) | Calculated based on experimentally observed decontamination rate using evaluation surfaces (~0.7 m2) |
| Efficacy Observations | Summary observations regarding the efficacy of the technology in removing contamination from the tested surface. |
| Operational Summary | Functional observations by decontamination technicians and project manager pertaining to efficacy, personal protective equipment (PPE) used, resulting airborne particulates, and training requirements for the home owner. |
| Method Cost (non-labor) | Estimate of cost considering only the low-tech radiological decontamination tools used during the experimental decontamination testing. Labor costs are not included in the estimate. |
| Fate of Activity | Detailed location of activity after use of low-tech decontamination tools (broom handles and heads, wipes, sponges, gloves, etc.) |
| Waste Stream | The activity level according to equipment components and tools used for decontamination. |
| Waste Summary (Indoor) | Based on the evaluation, an estimate of the amount and type of radiological waste that would be generated from decontamination of a typical house (using the most effective decontamination methods). The amount of waste is driven by the surface density of the fallout material as well as the weight of the equipment used. The evaluation assumed a 186 m2 (2,000 ft2) two-story house. The total solid waste generated was estimated to be 49 kilograms (kg). |
| Waste Summary (Outdoor) | An estimate of the amount (and types) of radiological waste that would be generated from decontamination of the exteriors of a typical house (using the most effective decontamination methods). For this estimate, the exterior of a two-story house was assumed to be 186 m2 (2,000 ft2). The total solid waste generated was estimated to be 181 kilograms (kg). |
| EPA Evaluation Report | Title of and link to the evaluation report for additional details and information. |
