Airborne Radiological Sampling Summary

Dear Mr. Reams,

Thank you for contracting Ameriphysics, LLC to provide environmental sampling and analysisservices for the project referenced above. On February 28, 2016, a total of 15 air samples were

collected at several locations within Estill County School buildings, outside these buildings

and within selected areas of the adjacent Blue Ridge Landfill.

Air samples analyzed by Ameriphysics, LLC demonstrate the samples contain naturally

occurring radionuclides at levels below allowable airborne concentrations listed in Title 10 ofthe Code of Federal Regulations Part 20 (10 CFR 20) Appendix B Table 2. These values are

used as indicated by 902 KAR 100:019 Section 11. Allowable airborne concentrations and air

sample results provided in Table 1 below are shown in microcuries per milliliter (µCi/ml).

Attachment 1 provides the Air Sample Log and the individual Air Sample Analysis Sheets for

samples identified in Table 1. Attachment 2 provides the air sampler and counting instrument

certification of calibration traceable to the National Institute of Standards and Technology.

We appreciate the opportunity to support your staff in this effort. If you have any questionsconcerning these results, please feel free to contact us at 800-563-7497.

Sincerely,

Elizabeth Gillenwalters, MS, CHP

Corporate Compliance Officer

viewing. The allowable concentration is based on Lead-210.

2. All values in this column are on the order of E-12. For example 1.42 is actually 1.42E-12. The exponent was removed for ease of

viewing. The allowable concentration is based on Actinium-288.3. Negative values are related to samples with activity less than the natural background values.
