A lot of people who make the world worse who don’t deserve to die of radiation sickness.
We don’t know anything about the hijackers other than that they committed this crime. How old are they? Are they parents? Were they involved willingly? Were their guns loaded? Why did they need the money? I’m not saying they’re good people. I’m saying we don’t know what kind of people they are. And if people who steal trucks at gunpoint deserve to die, then there’s no point in the concept of parole.
The Cobalt 60 source had an activity of 3000 Curies.
One Curie is equal to 3.6×1010 decays per second
Each 60Co atom emits two Gamma rays (1.17MeV, 1.33MeV) whilst decaying to 60Ni.
Therefore each decay of 60Co emits 2.5MeV worth of gamma rays.
One electron volt is 1.6×10-19 Joules
The power of the source
3000 Curies · 3.6×1010 Decays/second/Curie · 2.5MeV/Decay · 1.6×10-19 Joules/eV = 43 Joules / second = 43 Watts of gamma radiation (!) It really would be ‘hot’.
Decay of the source over time
The half-life of 60Co is ~ 5 years
maybe the source is 20 years old
so let’s divide that by 24 = 16 … still 2.6 Watts of Gamma radiation.
Toasting the thieves
A lethal dose of radiation is about 5 Joules / kilogram of bodyweight
The average mexican weighs 80kg ∴ we need 400 Joules to cook the thief
Suppose 10% of the γ-rays strike the thief vs. flying off into the sky or ground (the thief subtends 0.4π steradians)
To reach 400 Joules dose, he’d need to hold a 20-year old source for ~25 minutes to be sure of a lethal exposure (but only 90 seconds if the source was fresh)
It may be a scare tactic, but depending on what the thieves did with it, and how old/new the source was, it seems plausible they could be dead men walking.
Thought it through, and in context. They didn’t “deserve” it. But they did ask for it, at gunpoint. It isn’t my preferred outcome, but I’m afraid I don’t have much sympathy.
(If I was dealing with them directly, I’d probably have a bit more sympathy – for their suffering, not for their death. But since I’m not, and since there isn’t much that can be done about it, I have the luxury of not having to care.)
I’m certainly not saying that they deserved a painful death by radiation poisoning. But regardless of the circumstances they were flirting with death and putting themselves in harms way when they pulled a gun on the driver. Threatening to kill somebody is NOT a nonviolent crime, despite the fact that they did not, in the end carry out their threat. Would they have killed the driver if he attempted to defend himself? We don’t know. What the driver didn’t know was whether they’d let him live if he got out and gave them the keys. I don’t know what drove them to become violent criminals, but don’t kid yourself, they were violent criminals. Pulling a gun at somebody and threatening to kill them is NOT the same thing as, say hotwiring the truck and stealing it.
In 1991 The New Yorker published a 2-part bio of an artist named James Acord, who worked on just such a project. The problem of creating imagery that could communicate extreme danger across culture and time was one of his obsessions. In catching up with him on the Internet, I was saddened to learn that he committed suicide in 2011.
Strangest NRC license belonged to James Acord, who made his artwork using radioactive materials. He was so proud of being the first living individual to receive an NRC license (as opposed to a corporation) that he had the number tattooed on the back of his neck…
When I was young and stupid, I once opened a mysterious bucket. Guess what? It was full of rotten fish guts and I almost barfed. That was the last time I ever opened the mysterious bucket.
