Sample location not monitored during month

Regulatory Guidance = 50 mrem/yr

(see 10 CFR 20 Appendix B)

USACE Action Limit = 10 mrem/yr

(Suggested ALARA goal, 385-1-1, 3 September 1996)

The natural background radioactivity measured at the Sheridan Park water tower was subtracted from the measured radioactivity

at each sampler prior to calculating dose.
