Re: Quick question re: Acerinox incident



Dear Franz,



What I can add on this matter, is:



The caesium 137 source was not detected by the monitoring equipment and

entered the smelting process  in the Acerinox plant in Algeciras, releasing

a plume of contaminated off gases which triggered detection monitoring

equipment between 25 May and 2 June in France, Italy, Switzerland, Germany

and Austria and resulted in some temporary detection measurements up to

1,000 times higher than background radiation levels. Some detection points

were 2,500 km from Algeciras.  It was some days before the source of these

raised radiation levels was traced partly because the Acerinox chimney stack

mounted detection equipment failed,  and partly because of delays while

Spanish authorities double checked monitoring  data puzzled as to why raised

radiation levels were being detected. Reasons for non detecting: Small

activity or closed in the housing container with low dose at the surface.

For this scenario I have mentioned the importance of this incident to be

incorporated to training programmes on Emergency Response.

At the Dijon conference the US Nuclear Regulatory Commission (NRC) reported

that it is notified of about 200 lost or stolen radioactive sources each

year and that since 1983 20 sources had been accidentally melted at steel

works and  other foundries. According to other sources, 65 meltings have

occurred  world-wide . IAEA says it is aware of 49 meltings world-wide at

1998:

Dear José,



Thank you for this excellent summary. What I wonder, is, whether there is

any information available about the actual costs. They sure were much higher

than the costs for a portal monitor......



Best regards,



Franz
