In additon the pulse hel ht analyzer was reset to accept a b
broader energy range to assess other possible radionuclides in this region and the 15 minute count was repeated. Again, no significant difference from background level radiation was determine (

was requested to collect a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> urine sample which e subsequently returned to The Radiation Health Center for

,vo_lume and was subjected to radiometric analysis which included assessment for tritT.um, utilizing liquid scintillation counting techniques. The result of this assessment again revealed no significant deviation from background.
Assessment of aliquot of this 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> urine sample for gamma emitters utilizing sodium iodide crystal counting techniques did not reveal any significant deviation from background levels.
In summary,[r"~ _

to radioactive materials and/or ionizing radiation relating to his proximity to the Three Mile Island Generating Station on the ~=---
i i
I morning of March 28, 1979, while a passenger aboard a train passing that vicinity. Assessment of the patient consisted of radiometric analysis of the thyroid gland for evidence of 131I as well as other radionuclides, using standard scintillation detection techniques in nuclear medicine.
In addition, assessment of the trunk region utilizing uncollimated large field of view Anger gamma camera crystal detection field revealed no significant radioactivity level above that of background under identical conditions. Radiometric assay of a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> urine sample which I
included assessment for gamma emitters by sodium iodide scintillatior i
detection methodology and assessment for tritium with scintillation counting techniques again revealed no evidence above oackground.
A brief report of our findings, that is finding no evidence of radioactivity levels above that of natural backg ound, has been made available to the patient.
If we may assist you further regarding this case, please advise the undersigned and we will be pleased to respond, S neerely yours
