Best reply on this thread. Everything in Australia kills you or at least causes horrible pain. Even that cute platypus or that harmless-looking shell on the beach. And now this.
No moose, bears, wolves, cougars, or other alpha predators in Australia though. About the worst are wild dogs / dingos, though they typically won't be a problem unless they're in a pack. I'll take Australian dangers over North American every day of the week.

#182Related but off topic question. Why isn't radiation used for food preservation?

This is the nature of highly radioactive materials. Walk past it? No problem. Walk on the crushed capsule, brush your hand against the bottom of your shoe, eat a sandwich? Die horribly.
Hyperbole. "the equivalent of 10 X-rays in an hour" So no, walk on it and you would never know. Nobody dies, not without carrying it around for days. Then they get burns. It's important to understand the numbers - and the magnitude of this radiation source is concerning but not dire.

#184They should issue a nationwide announcement for people to check their tires for the lodged capsule.

The equipment to detect high levels of radiation is very cheap. Likewise the equipment to detect lead... And hundreds of other deadly pollutants. Part of owning a house should involve getting it tested, perhaps once per 10 years, for all these contaminants. They might have been put in during construction - or it might be arsenic in the wood of your bed... Or a mixing mistake while making the plastic for your toothbru…
Are there testing services you’ve used before or would recommend to perform the testing? There does not seem to be a major brand or service provider offering this. Thank you!

Again, hyperbole. "the equivalent of 10 X-rays in an hour" People routinely get exposed to that during their normal job. An x-ray is a fraction of a year's natural exposure from the sun. Airline pilots experience this radiation in a few months at work. The numbers matter. This instance, the device hardly matters. Not as much as a national news report anyway. We'd be better off reading about pay disparity or access to…
To back up your point: If "X-ray" is a chest x-ray, then per https://xkcd.com/radiation/ this would be equivalent to one-tenth of a head CT scan, which are routinely done without consideration to any increased risk of cancer. If the goal is to minimize loss of life, I think there are far better things that time could be spent on than looking for this thing. People are bad at thinking about opportunity cost.

#187Radiation detection is my specialty. This source is Cs-137, few hundred mCi. It's easy to detect within a few seconds at distances of a few tens of meters or more with professional detection equipment if there is direct line of sight. If it was knocked off the road, though, the question will be if it fell into a crack or other such place because then the radiation is somewhat shielded and it would take much more meas…
...or if there is already a crowdsourced detection effort for looking out for this sort of thing, that'd be a cool map to plot.

#188Here's a story about a lost capsule[0] that ended up being made into building material for the wall of an apartment if you think something small isn't worth being concerned about. [0] https://en.wikipedia.org/wiki/Kramatorsk_radiological_accide...

There's documented incidents of radiation burns (https://jamanetwork.com/journals/jama/article-abstract/33268...) and cancer (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1451360/).

Most Americans would still choose not to do this because any knowledge of a positive lead test means that you need to report it when you sell your house which might effect resale value. The large majority (>90%) of houses built before 1940 have lead paint in them somewhere and lead paint wasn't banned until 1970 in the US so many older houses still have lead paint somewhere
Presumably if you care about testing for lead, you'd also care enough to have it dealt with while you are living there.
