So... I've been playing a lot of the video game Subnautica lately, which put me in the mood for a "trying to cope with being marooned on an alien planet" sort of story; however, there's something in the game that's made me wonder about the logistics of a particular problem.
At one point in the game, you don a Radiation Suit and return to the crashed remains of your former spaceship in order to contain the radiation leak from when the FTL Drive Core blew up post-crash and keep it from spreading any further; while you're there, you discover that some parts of the ship are still surprisingly intact, including some of the crew quarters, and you can scavenge and collect various items for use in your own "base camp", including components for new technologies. In addition, you can also collect various decorative items that presumably belonged to the ship's late crew members, such as a model spaceship and a large plush toy.
This inspired me to include a scene of someone attempting similar containment of radiation from a crashed vessel discovering that some items belonging to a fellow officer's children - who survived the crash and who are now obviously feeling distressed and afraid back at the group's temporary shelter - and decides to bring the toys back to camp with them to return some sense of normalcy to the children's lives. However, given their close proximity to a large and presumably nuclear explosion and the continued leakage of radioactivity into the surrounding ocean, could something like a plastic model ship or a soft cloth toy be safely cleansed of radiation?
Some details about the explosion that might be useful:
Here’s some footage of the actual explosion and the description your PDA gives you, I’m not 100% sure if anyone can discern anything from this but I thought I’d include it anyway: https://youtu.be/rIlxEJG5whU
The ship seems to use a lot of titanium, according to some flavor text on one of the equipment pieces
The crash took place on an ocean planet, and so the remainder of the ship was partially submerged in a large body of water (I think I remember learning something about water affecting the spread of radiation differently than air? Please correct me if I'm wrong about that). For the purposes of making this easier, let's say our marooned group also crashed their ship into a sizable body of water
The actual compromised "Drive Core" was underwater, while the portion of the ship where the relatively intact crew quarters were was still above water and, if I remember correctly, positioned a few floors up and at the opposite end of the wreckage, so the objects in question likely never came into contact with any material leaking from the drive core post-explosion, if that matters? The crew quarters also still seemed to be sealed for the most part.
I'm not sure what the Drive Core was made of or how it worked (the game gives you some technobabble about a "Dark-matter ion drive core", whatever that means), but it seems like there was at least some uranium involved, as a lot of the other nuclear-powered tech options in the game use it, so that's probably a good basis for what sort of thing we're dealing with here
These items are being retrieved somewhere between 24 hours and 2.5 weeks after the initial explosion/event; exactly when in that window may depend on the answer to this question
So, with the above parameters in mind, here is my question: Would this kindhearted gesture be possible without horribly irradiating the Kids? Or would the would-be hero have to leave the toys behind due to health risks?
In fact, while we're on the subject, could your character in the GAME safely repurpose these items? Or is he going to survive the crash, the unforgiving elements, and the hostile alien wildlife, only to succumb to unexpected radiation poisoning?
