A customer needs to reach an RL of 200 ug/ft2 and 40 ug/ft2 and wants to verify the recommended or minimum sampling areas.
| The current FLAA RL is 10 micrograms per sq. ft. based upon a 144 sq. in. wipe area. The RL goes up proportionately as the area goes down. For example, an RL of 40 micrograms per sq. ft. could be achieved with a 36 sq. in. wipe area. |
