Small amounts of Iodine-131 have been detected at the Nine Mile Point and Ginna sites this week.

While site personnel believe it is fallout from the events in Japan, the licensee has not informed the public or the state of New York as they continue their investigation of the source. Please note in the email below that the term outfall was erroneously used. The email should have stated that the contamination was observed in stormdrains. 

According to Glenn Dentel, Iodine-131 has only been observed at Diablo Canyon and the two New York sites below.

FYI, more information on the RIS. By the way, now Limerick and TMI are reporting having found 1-131 in rainwater samples. I’ve passed along results to Richard Conatser.

Subject: RIS to licensees on radioisotopes that are detected from the Japanese event

All,

NRR has been directed to develop a RIS to the licensees regarding radioisotopes detected by the REMP program that are from the Japanese event. This RIS will request that the licensees voluntarily submit their results to the Operations Center at hoo.hov•,nrc.pov. In parallel, NEI will also be requesting the information from the licensees. This is the information we are requesting:

When reporting information, the following should be provided as applicable:
1 Sample date(s) and time
2 Approximate locations(s)
3 Environmental sample medium (eg, air particulate filter, air charcoal, milk, sediment, vegetation, rainwater, groundwater, etc…)
4 Type of analysis (eg, gross beta, iodine-131, tritium, etc…)
5 Analysis result(s) (in units typically used in the environmental monitoring program and include applicable detection sensitivity)

If you have any questions, please let me know.
