JIM WIGGINS: Have they been venting? We need to know. Unit 3.
MALE PARTICIPANT: You mentioned 150 millirem per hour.
JOHN MONNINGER: The — are you ready?
They took some samples, and the sample is in microcuries per milliliter, and they say that’s the equivalent of 150 millirem per hour.
MARTY VIRGILIO: Okay, so it’s an air sample and they converted into (inaudible) hour.
JOHN MONNINGER: Yeah.
MARTY VIRGILIO: Okay. All right.
JIM WIGGINS: And where did you say they caught these samples?
JOHN MONNINGER: It’s either –
MALE PARTICIPANT: Yokohama?
JOHN MONNINGER: — pronouncing it correctly — Yokashawa or Yokohama.
JIM WIGGINS: Well, there’s Yakota Air Force Base and there’s Yokuska Submarine Base.
JOHN MONNINGER: Yeah. I don’t know which one, but we, you know, the thought is to get in touch with the Navy and figure out where they took the sample and what this write-up means.
MALE PARTICIPANT: Did you mention some Navy Admiral?
JOHN MONNINGER: Admiral Thomas. The information is from 11:30 a.m. out here, which is approximately an hour and a half ago.
KATHY: We got information — I just wrote down here “Navy guy.”
MARTY VIRGILIO: Admiral Thomas was the Navy guy.
MARTY VIRGILIO: Go ahead.
KATHY: And they took a sample. The sample point they gave us, the latitude and longitude, is an area south of Tokyo.
JOHN MONNINGER: So thyroid dose, okay.
KATHY: Yeah. And they asked us if we can back-calculate a dose in Tokyo. We wanted to try to do that. RASCAL won’t do it. It will be have to be hand-calculated. But then we got a (inaudible) from Bill Cook. Is he with you, John?
JOHN MONNINGER: Yes, Bill Cook’s with us.
KATHY: Okay, so we’ll just talk to him if they’re concerned about (inaudible) number 2.
MARTY VIRGILIO: Yeah, I didn’t hear the last — I, they’re concerned about evacuating the embassy, or US citizens?
KATHY: Yeah. What, what we want to do is get, get in touch with the people that actually pulled their samples so we can get more information on how they pulled the sample.
JOHN MONNINGER: Right. And we concur 100 percent in that, the notion that we talk to the Navy, come to a complete understanding, and maybe there’s recommendI ations out of that; ma there data
MALE PARTICIPANT: But the source term we (inaudible) from that was 1.6 10-6 microcuries per milliliter.
MARTY VIRGILIO: Which is clearly a level of interest. It’s higher than the numbers I’ve heard from the more –
JOHN MONNINGER: So what were you told about the equivalent thyroid?
KATHY: 1.5 millirem per hour.
JOHN MONNINGER: So that’s a factor of 100 different than what’s being reported here.
MALE PARTICIPANT: Yeah.
JOHN MONNINGER: They’re saying 150 millirem per hour.
JOHN MONNINGER: And that’s what’s, being briefed to the ambassador right now.
KATHY: Whether they have any other sample.
MALE PARTICIPANT: We need to be clear on where that sample is collected.
KATHY: We, we have a latitude and longitude.
MARTY VIRGILIO: Can, can you read that to me?
KATHY: 36.11.46 N.
MARTY VIRGILIO: 36.11.46 N.
KATHY: 120.16.87 E. We’re told that it’s south of Tokyo.
