Update (10/22): Status of patients from the JCO Criticality



RADSAFERS,

Science and Technology Agency started publishing newsletters to keep the local
public informed. The 10/15 issue can be found at "
http://sta-atm.jst.go.jp/news_letter.html";  It is a image file. Even if you
can't read Japanese, you can see the flowchart and figure out what happened.

"http://www.jca.apc.org/gensuikin/tokai/hibaku_jco.gif"; is table of estimated
external dose and surface contamination level for JCO workers. Column 1: Name
(erased); Column 2: Start of accident; Column 3: Start of count; Column 4:
Elapsed time; Column 5: Na-24 activity as measured by whole body counter in Bq.;
Column 6: Decay corrected Na-24 (Bq); Column 7: Estimated dose [mGy] (neutron +
gamma); and Column 8: Body surface contamination.(all on head, and one bottom of
left shoe)

Notes at the bottom of the table are: "Note 1: Na-24 value of 1Bq = 0.5 - 3 uGy
used (from IAEA Technical Series No. 211)"; "Note 2: Surface measurement limit
40 Bq/cm^2"; "Note 3: Na-24 detection limit 100 Bq."

Hand-written note at the bottom are revealing. "Completed decon of people with
contamination"; "Fraction of neutron is unknown"; "It is difficult to calculate
dose in mSv"; and "Large uncertainty in mGy."

transfusion of RBCs and platelets is required. There is concern for
complications due to infection, but thus far there is no sign of infection. No
bowel movement or blood in stool. Treatment Direction: Continue with

transfusion of RBCs and platelets. WBC count has increased. Performing
evaluation to determine if borrow marrow transplant was successful. Appearance
of radiation burn changed. The color is dark red, and blisters appearing in
upper right thigh. It is unclear if there is infection. No bowel movement.
Treatment Direction: Will evaluate the trend of WBC to determine if bone marrow
was successful. Still evaluating feasibility of ?direct feeding method to
intestine.? Continue ventilation management, infection prevention, nutrition
management, continued transfusion management, and detailed total body
management.
Others: Vigilance must be maintained.

BP: 130/58 mm Hg         Pulse: 120/min.
Resp: 12/min.            Temp: 37.8 C
Providing sedative and continuing with ventilation. X-ray reveals increase in
lung damage, but oxygen intake is satisfactory. Renal function stable. Rate of
RBC and platelet decrease has eased. WBC count had increased rapidly, confirming
the success of bone barrow transplant. It is still unclear if there is
infection. There was diarrhea but no blood in stool.

was successful. Still evaluating feasibility of ?direct feeding method to
intestine.? Continue ventilation management, infection prevention, nutrition
management, continued transfusion management, and detailed total body
