I know about the existence of certain windows for which it is more suitable to launch a probe for the exploration of a cellestial body in our Solar System (see the Wikipedia Launch window). I wondered about a different problem.
In the past, if I refer well there was in the literature projects to build certain structures (you can to illustrate your answer with a generic example or with a specific one) in low orbits around of our planet Earth: for example a (great) spacecraft, telescope (we evoke a very big telescope) or a space elevator.
Question. I would like to know what is the more suitable period in terms of the expossition of radiation that is allowed for our workers, I mean an approximation of the date(s) of the more suitable periods, with a deadline for our project in next $30$ years (or few decades from your discussion) in which I evoke the fictious situation that we want/need (and we can in this thought experiment) to build a great construction project in a low orbit similar than the orbit of the International Space Station or other low orbit more suitable (see below again the requirement in the context of our ficticious project, since we want to minimize the radiation for our workers). Many thanks.
Thus you add an answer as a draft of computations or estimations for our generic project, you can to add all those variables that you need in your computations for our great project in order to get a more precise answer (if possible).
Important goal/assumption. While our workers have the possibility to save their bodies of radiation (this radiation in a wider meaning of ther word, but that I mean are the more probable conditions, I emphasize radiation exposure, that scientists should to expect in next few decades) eventually in shelters or those conventional protection means for the astronauts, we want to minimize this impact of radiation in their bodies and to know an approximation of when will be a suitable period/date for do a work of building of a great project in next few decades (for this thought experiment we evoke that the starting of activities for this ficticious project is at this year $2020$).
If my question is in the literature (or you know remarkable articles in this context), then please refer the literature answering my question as a reference request and I try to search and read the answer for my question from the literature.
