Good question. I'm not sure about the specifics of the stackoverflow poster's application, but for my case, they're used in space.
It's my understanding that you would need a very thick layer of metal to actually protect a device. Generally, lead works, but the thickness required would mean that your device would be extremely heavy. However, like you said, this isn't a problem for ground applications.
Also, apparently water works well too.
This is all honestly beyond my knowledge though. Our customers do their own qualification since these are COTS devices, so any failures may be handled on their end by making separate enclosures or using another vendor's system as a backup. They haven't actually asked us to implement any software based risk mitigation, but I investigated it on my own.
- 0xFFC 11y agoAnother stupid question, can you suggest a reading about reliable software development ? (I prefer book) BTW thank you for excellent information in your comment.
- Unklejoe 11y agoSadly, I don't know of any good resources. It's kind of a specific topic, and it wasn't really part of my task to consider these issues, so I only spent a small amount of time researching it myself. I believe most of the studies were conducted by NASA, so incorporating that into a search should help.

Some experiments have used 2000 year old Roman lead to avoid this http://www.nature.com/news/2010/100415/full/news.2010.186.html http://www.nature.com/news/2010/100415/full/news.2010.186.ht...
