Good news. The procedure worked. Mostly.
The official report back is that the current background levels of radiation are higher than they should be, but not lethal in the near future, and so whilst they work out how to secure the – what I now appreciate is – a nuclear reactor in the engine of this ship, I should get back to life as normal, and continue my treatments until they tell me to stop.
So am back on to my routine. Exercise, stare out the window, float a little, watch TV, watch movies, read, look after the ants, do chores, write these posts. I’ve checked, and I can actually start studying engineering based on the library here, which wouldn’t be a terrible idea.
