ERD is published in both hard-copy and electronic formats. Electronic reports are available online at http://www.epa.gov/narel. RadNet data are also available online in a searchable database at: http://www.epa.gov/enviro/facts/radnet The United States Environmental Protection Agency established RadNet in 1973 with an emphasis on identifying trends in the accumulation of long-lived radionuclides in the environ- ment. RadNet is comprised of a nationwide network of sampling stations that provide air particulate, precipitation, drinking water, and milk samples. Sampling locations are selected to provide population and geographic coverage for the United States. The radiation analyses performed on RadNet samples may include gross alpha and gross beta analysis, gamma analyses, and radionuclide-specific analyses for isotopes of uranium, plutonium, strontium, iodine, radium, and tritium. This monitoring effort also provides informa- tion on natural background levels and possible accidental releases into the environment. vii ------- This page intentionally left blank viii ------- Acknowledgments All sampling for the RadNet monitoring system (formerly ERAMS) is performed by volunteer collectors who are frequently members of health departments or related environmental agencies of their respective states. The National Analytical Radiation Environmental Laboratory (NAREL), on behalf of the U.S. Environmental Protection Agency, would like to acknowledge the time and effort of these volunteer collectors, who are so essential to the successful operation of RadNet. The efforts of the sample collectors are especially appreciated during times of emergency operation when sampling frequencies are increased and schedules are sometimes demanding. IX ------- This page intentionally left blank x ------- Data Reporting Conventions Every laboratory measurement involves uncertainty. When there is little or no radioactivity in a sample, one consequence of measurement uncertainty is the possibility of obtaining a measured value that is less than zero. Such a negative result occurs when random effects in the measure- ment process cause the measured value for the sample to be less than that of the blank or back- ground, which is subtracted from it. From April 1991 to December 1995, negative results were reported as "not detected" or "ND," and gamma analysis results that were less than their estimated measurement uncertainties were also reported as "ND." In January 1996, both of these practices were discontinued. Although negative activities are physically impossible, the inclusion of negative results in the report allows better statistical analysis of the data. Results of gamma analyses are still reported as "ND" when gamma-emitting radionuclides are not detected. Measurement Uncertainty Each measured valuey is reported with an expanded uncertainty U=k uc(y), which is determined from the combined standard uncertainty uc(y) and the coverage factor k = 2. The interval from y - Utoy + C/ is estimated to have a level of confidence of approximately 95 %. Significant Figures Expanded uncertainties are reported to two significant figures. Measurement results are rounded to the corresponding number of decimal places. Detection Capability The minimum detectable concentrations (MDCs) for each radionuclide are shown in Table 1. The MDC is defined as the minimum concentration that gives a 95 % probability of detection when the detection criteria are chosen to give only a 5 % probability of false detection in a sample that is analyte-free.

Air Program Airborne Particulates and Precipitation Gross beta radioactivity measurements and certain specific analyses are performed on air partic- ulates and precipitation samples as indicator measurements in assessing the general (national) impact of all contributing sources on environmental levels of radiation. Continuous air samplers collect airborne particulates at field stations representing wide geographic coverage throughout the United States. Filters (10 cm diameter synthetic fiber) from air samplers are changed routinely, and generally field measurements are made with a dual-phosphor scintillation counter at least 5 hours after collection to allow 222Rn progeny to decay. Field estimates are reported to appropriate EPA officials by telephone or mail depending on the activity levels found; however, as of the first quarter of 2012, NAREL no longer reports field estimates in Environmental Radiation Data. The filters are sent to NAREL for more sensitive analysis in a gas proportional counter. Gamma scans are performed on all filters showing gross beta activity greater than 1 pCi/m3. All stations routinely submit precipitation samples as rainfall, snow, or sleet occurs. The precip- itation samples are composited at NAREL into single monthly samples for each station. Each month that precipitation occurs, an aliquant of the composited sample is analyzed for gamma- emitting radionuclides. NAREL discontinued gross beta analysis of precipitation in January 2010 and discontinued tritium analysis of precipitation in January 2012. 1 ------- Table 2 Gross Beta in Airborne Particulates July 2013 NAREL Lab Number Measurement of Max Min Avj?

Plutonium and uranium results are published in the ERD for the third quarter of the following year. Concentrations of plutonium-238, combined plutonium-239 and 240, and uranium-234, 235, and 238 are determined by alpha-particle spectrometry following chemical separation. The total volume of air represented by all the samples received from one sampling location during a year typically ranges from 120,000 m3 to 500,000 m3. The aliquot analyzed is a fraction of the total volume and is typically between 5,000 m3 and 30,000 m3. 17 ------- Table 8 Plutonium and Uranium in Airborne Particulates January-December 2012

Drinking Water Program The RadNet drinking water program provides data on radionuclide concentrations in the nation's drinking water supplies. Sampling sites are either major population centers or selected nuclear facility environs. Drinking water data are used to assess trends and anomalies in concentrations. The analysis scheme for RadNet samples is similar to that of EPA's "National Interim Primary Drinking Water Regulations." The analyses include (a) tritium on a quarterly basis; (b) gross alpha, gross beta, and gamma on annual composites; (c) radium-226 if the gross alpha exceeds 2 pCi/L and radium-228 if the radium-226 falls between 3 and 5 pCi/L on annual composites; (d) iodine-131 on one quarterly sample per year for each station; (e) plutonium-238, combined plutonium-239 and 240, and uranium-234, 235, and 238 for stations that demonstrate gross alpha levels greater than 2 pCi/L on annual composites; and (f) strontium-90 on one-fourth of the annual composites on a four year rotating schedule. Composite results are published in the ERD for the third quarter of the following year. RadNet drinking water data should not be used to monitor compliance with drinking water regu- lations or for comparisons to those data since different procedures for collection and analysis may be used. 23 ------- Table 9 Tritium in Drinking Water July-September 2013 Date 3H Location Collected pCi/L ± 2u AK: Fairbanks 07/30/13 0 81 AL: Dothan 07/09/13 21 83 AL: Montgomery 07/08/13 23 84 AL: Muscle Shoals 07/02/13 30 80 AL: Scottsboro 07/01/13 4 79 AR: Little Rock 07/02/13 -39 77 CO: Denver 07/08/13 27 84 CT: Hartford 07/02/13 50 85 DE: Dover 08/01/13 -47 79 FL: Tampa 07/11/13 -17 82 GA: Baxley 07/16/13 50 84 GA: Savannah 09/11/13 -32 91 HI: Honolulu 08/12/13 -53 78 IA: Cedar Rapids 07/10/13 17 83 ID: Boise 07/08/13 8 83 ID: Idaho Falls 07/18/13 11 81 IL: W.

Milk Program Pasteurized Milk Milk is a reliable indicator of the general population's intake of certain radionuclides since it is consumed fresh by a large segment of the population and can contain several of the biologically significant radionuclides that result from environmental releases from nuclear activities. A primary function of this program is to obtain reliable monitoring data relative to current radio- nuclide concentrations and determine any long-term trends. Milk samples are collected quarterly at each of the sampling sites. The samples are analyzed for gamma-emitting nuclides, including iodine-131, barium-140, cesium-137, and potassium-40. Total potassium concentrations in g/L are determined from potassium-40 activities assuming natural isotopic abundances. During the third quarter collection, one-fourth of the samples are also analyzed for strontium-90 on a four year rotating schedule. 39 ------- Table 13 Radionuclides in Pasteurized Milk July-September 2013 Date K 137Cs 140Ba 131j Location Collected g/L ± 2 u pCi/L ± lu pCi/L ± 2u pCi/L ± 2m AR: Little Rock 07/29/13 1.62 0.19 ND ND ND AZ: Phoenix 07/17/13 1.63 0.19 ND ND NR CA: Los Angeles 09/25/13 1.55 0.18 ND ND ND CA: San Francisco 07/15/13 1.90 0.22 ND ND NR CT: Hartford 09/04/13 1.61 0.19 ND ND ND DE: Wilmington 07/15/13 1.70 0.20 ND ND NR FL: Plant City 07/23/13 1.64 0.19 ND ND ND HI: Hilo 07/10/13 1.65 0.20 ND ND ND IA: Des Moines 08/19/13 1.60 0.19 ND ND ND KS: Wichita 08/29/13 1.68 0.20 ND ND ND KY: Louisville 07/08/13 1.66 0.20 ND ND ND MA: Boston 09/12/13 1.65 0.20 ND ND ND MD: Baltimore 07/08/13 1.61 0.19 ND ND ND MO: Jefferson City 08/06/13 1.64 0.19 ND ND ND NJ: Trenton 07/12/13 1.60 0.19 ND ND ND NM: Albuquerque 08/30/13 1.52 0.18 ND ND ND NV: Las Vegas 08/12/13 1.80 0.21 ND ND ND NY: Buffalo 08/07/13 1.62 0.19 ND ND ND NY: Syracuse 07/16/13 1.65 0.20 ND ND NR OH: Cincinnati 08/19/13 1.69 0.20 ND ND ND OH: Cleveland 08/02/13 1.69 0.20 ND ND ND OR: Portland 09/17/13 1.60 0.18 ND ND ND PA: Pittsburgh 07/23/13 1.66 0.19 ND ND ND TN: Chattanooga 09/25/13 1.61 0.19 ND ND ND TN: Knoxville 08/09/13 1.67 0.20 ND ND ND TN: Memphis 07/08/13 1.58 0.19 ND ND ND TX: Dallas 08/20/13 1.64 0.19 ND ND ND TX: San Antonio 07/08/13 1.65 0.20 ND ND ND VT: Montpelier 07/17/13 1.70 0.19 ND ND NR WA: Spokane 08/07/13 1.79 0.20 ND ND ND WA: Tacoma 09/28/13 1.63 0.19 ND ND ND WV: Charleston 07/10/13 1.64 0.19 ND ND ND Note: ND = Not detected NR = No result (not analyzed within 5 half-lives of collection) 40 ------- Table 14 Strontium-90 in Pasteurized Milk July-September 2013 Date 90Sr Location Collected pCi/L ± 2u CA: Los Angeles 09/25/13 0.33 0.41 CA: San Francisco 07/15/13 -0.33 0.40 FL: Plant City 07/23/13 0.25 0.46 MO: Jefferson City 08/06/13 0.08 0.65 NY: Syracuse 07/16/13 0.64 0.94 PA: Pittsburgh 07/23/13 0.46 0.51 TN: Chattanooga 09/25/13 0.83 0.53 VT: Montpelier 07/17/13 0.35 0.45 41 ------- This page intentionally left blank 42 ------- For More Information Environmental Radiation Data (ERD) is published quarterly by the U.S. Environmental Protection Agency's Office of Radiation and Indoor Air.
