  1. Environmental Radioactivity Measurement Facility Department of Oceanography Florida State University Tallahassee, Florida USA

  2. Objectives • Study the distribution of U/Th decay-series nuclides to address problems in the earth/marine sciences. • Improve chemical and instrumental techniques for measurement of all radionuclides in the environment.

  3. 222Rn 210Pb 222Rn 222Rn 234Th 226Ra 234U 238U 230Th var. ~10 dpm/100L: 237 <1 271 Seawater ~50 238U ~ 3.2 g/L 226Ra Sediments 230Th (234Th, 231Pa, 210Pb, etc.) U-Series Disequilibrium in the Ocean R/V Eichrom

  4. Funding • Federal: NSF, ONR, NOAA, EPA • State: FDEP, FIPR, FDOH • Private: PG Research Foundation, ACS, Earthwatch

  5. Current Projects • Tracing of groundwater discharge into the coastal zone via Rn-222, radium isotopes • Automated Rn-222 in water and improved Ra-224 via Mn-fiber/Rn counting • Radioanalytical analysis of large volume environmental samples via Diphonix • Th-234 in marine sediments via extraction chromatography - LSC

  6. Graduate Students - M.S. Jamie Christoff Michael Lambert

  7. Graduate Students - Ph.D. Henrieta Dulaiova Svetlana Nour

  9. Undergraduates Igor Nathan

  10. “Bill…you need to use Diphonix resin to remove sample matrix and make your life easier” Scientific Advisor I wonder when FSU is going to play a real football team…

  11. It…Could…Work…!!! Remove the Sample Matrix…?
