Re: Screening Techniques: Goiania
Dear Dr. Carol Marcus,
Please find the answer of your questions in the two following IAEA documents available to download.
Due restriction of the Radsafe List, by separate e-mail I sent 7 pictures showing phases of screening and the main equipment used. It was scintillometer detector type Saphymo-SRAT S.P.P.2 NF, 1x1.5 inch, NaI(Tl) scintillation crystal and the operational range for gamma radiation is 0.02 to 30 µSv/h. The instrument has a built in audible alarm that gives a high signal. The unit of measurements used by the SRAT is cps. The size of the instrument is 32x13x12 cm and the weight, 3.6 kg. This is the same type of detector used in the IAEA's Georgia Mission more than 10 years after Goiania, compare the pictures in Goiania and Georgia. We have used this kind of equipment during many years to uranium prospecting in Brazil.

Look also the following papers at the Health Physics 60(1) 1991 - Special Issue The Goiania Radiation Accident:

Dear colleagues, now considering Dr. Carol's topic, how could be the initial response in Madrid if with the explosives it was also added a source with the activity in Goiania?
