This part seemed quite crazy, though: "She was buried in a common cemetery in Goiânia, in a special fiberglass coffin lined with lead to prevent the spread of radiation. Despite these measures, there was still a riot in the cemetery where over 2,000 people, fearing that her corpse would poison the surrounding area, tried to prevent her burial by using stones and bricks to block the cemetery roadway."
I'm not saying that the coffin was insufficient protection, but I know I don't know enough to be sure. So the question is not "am I well informed enough to judge the risk" (and in a country with good education standards and having studied physics to 18 I probably have a relatively decent education) but rather "do i believe that the person who made that judgement was".
Also, as an adult, I've spent several years living all over Brazil so I'm familiar with their education system and religious beliefs. I don't find the riot so strange when considering the experiences I had in Brazil.
If you guarantee that "hey! nuclear stuff is absolutely safe, there will never be problems whatsoever!", but then incidents happen, it's reasonable that people is skeptical when you say "hey! that coffin is absolutely safe, there will never be problems whatsoever!".
This could be extended as a reasonable doubt of nuclear energy in general (I don't claim to support it; just accept it as reasonable).
I understand that radiation isn't magic and things don't become permanently tainted by mere exposure.
Still, this girl ingested cesium and died as a result.
I would be highly uncomfortable with with an unknown quantify of a beta+gamma emitter with a 30 year half life being buried anywhere near where I get my family's drinking water.
People are scared of nuclear technology in no small part because they simply don't understand it.
