Re: Public info, risk perception and fear of nuclear
Thank you for both information
As you have mentioned, once the network is totally independent from the
owner of the nuclear site, the credibility will be also important in terms
of public communication.
Such effectiveness can be demonstrated with the Incident of Acerinox. At the
end of May 1998 a Cs-137 source was melted accidentally in one of the
stainless steel production plant furnaces that the ACERINOX company has in
Cadiz (Spain), this activated alarm systems in southern France, the French
independent laboratory CRII-Rad (Commission de Recherche et d'Information
Independantes sur la Radioactivite) has detected high levels of
radioactivity coming from ashes of the factory of Acerinox and this was the
first indication of something was wrong. Even the Spanish Regulatory
Authority, Consejo de Seguridad Nuclear (CSN) didn't know at that moment. I
have papers on this incident, however there is no mention that the first
detection was out of Spain, this detail came from the press, (besides France
also Italy, Swissland and German have detected).
Inclusive Decontamination took 5 months, and 50.000 man-hours were necessary
to perform the whole work and approximately 2000 Ton of low level activity
wastes were produced in the decontamination, however there is no document
about the activity of the Cs-137 source.
If you have any other detail, please let us know, if possible

Subject: RE: Public info, risk perception and fear of nuclear
I'd like to add information about the Teleray network, which is monitored
from my department.
Today, 157 stations are being operated in France and 22 in overseas French
territories or foreign countries. One is located in New York. The data can
be comsulted on the web at the adress given by Philippe Duport. They are
updated every day.
In France, there are stations near each nuclear site (NPP, reprocessing
plant,military sites,...)
The network is totally independent from the owner of the nuclear site.
The sensitivity of the probes is 10 nGy/h, so that they can even detect a
small rise of radon concentration due to a storm. The range of measurement
is 10 nGy/h-10 Gy/h.
In normal days, a mean value of the dose rate is calculated every hour and
the stations are called once a day to obtain these datas.
This operating mode can be changed if needed.
What is more, if an incident occurs and triggers an alarm in one station,
this station automatically send its data to Le Vesinet, where the control
room is located, and mean values are calculated and sent every 5 minutes.
If you want more information about this network, contact me privately.
