The prescribed prescribed year ends August 31 for the UFTR. This annual operating operating report includes 7 sections:

(The summary shall include to the extent practicable an estimate of individual radionuclides present in the effluent. If If the estimated average average release after dilution or diffusion is less than 25% 25% of the concentration allowed, a statement concentration statement to this effect is sufficient.);

(6) A summarized summarized result of environmental surveys performed outside the facility; (7) A summary of exposure (7) exposure received by facility personnel and visitors where such exposures exposures are greater than 25% 25% of that allowed.

The following discussion on the above seven sections covers the period from from September September 1, 1, 2005 to August 31, 31, 2006, except as noted otherwise.

. In the past reporting year, UFTR continues to function as a reliable and productive facility with a broad range of research and educational educational utilizations by users within within (

University of Florida Florida as well as researchers researchers and educators educators around the State of Florida.

And as a milestone milestone year, the UFTR facility has completed the REU HEU to LEU fuel conversion project.

The firm maintaining maintaining radiation radiation records for the University University of of Florida Florida keeps keeps a year to date date record, therefore therefore it is easier easier to report radiation radiation exposure exposure by the nearest nearest completed completed calendar calendar year.

The following film badge exposures exposures are for the period January January 1, 1, 2005 2005 to December December 31, 31, 2005.

2005.

Thirteen Thirteen areas (Numb~r~d (Numbered from I 13) 1 to 13) were monitored monitored for the entire calendar calendar year. A list of these numbered numbered areas can be found in UFTR SOP. Note that among among them, Area No.

No.2, 2, which is the stack ~tack area, area, has the the highest dose record. And 33 separate separate areas areas in in the reactor reactor building we~e monitored building were monitored during during the same same time period. The area radiation radiation exposures are tabulated exposures tabulated below. All doses doses are in in unit of mrem.
