Please close this action. I left a voice message with Bill Maier. If he has follow-up questions he will call us through the HOO.

I just got off the phone with Aubrey Godwin, Director of the Arizona Radiation Regulatory Agency (ARRA) and Arizona State Liaison Officer to the NRC.

Mr. Godwin is planning to issue a news release following up on the attached. Mr. Godwin was aware of Palo Verde’s confirmed measurement(s), so the licensee is in communication with the State about its findings.

One of the items Mr. Godwin needs to include in his follow-up news release is the air concentration of iodine that would prompt the recommendation, following the present Federal guidance, for persons to ingest potassium iodide. Mr. Godwin is asking for NRC input to check the calculated value which he proposes to include in his news release.

That calculated value is 1000 picoCuries per cubic meter of air, or 1000E-12 microCuries per millileter of air

Mr. Godwin did not elaborate on what assumptions contributed to the derivation of that value, but he is asking for an independent calculation from the NRC that would confirm or deny the feasibility of the above value.

He asked that the answer to this request be expedited, if possible, because he informed me he has to issue this news release soon (a few hours).
