so currently in real life there are three types of radiations: alfa, beta, and gamma only gamma radiation can not be manipulated using magnets (both electro, and natural ones) as it is neutral however both alfa, and beta radiations can be manipulated using magnets so maybe some planets the player might start on playing one of these new types of radiations (either alfa, or beta, possibly both named "weaker radiation") may be present unlike gamma radiation that may be present on more difficult planets - against which alfa, and beta radiations the player can build "portable electromagnets" that will consume fuel in order to make a small area around it protected against some radiation strength - analogous to the portable heater iron ore may be a natural magnet on planet surfaces, so maybe if alfa, and beta radiation strength were not as strong near to iron ore on such alfa, or beta radiated planets compared to other regions of those planets would be nice also the player can just build its base out of wood in order to protect it against radiation, but what if you were to include a low tier material: lead, (and possibly later tier bismuth) that can protect a structure's internal compartments against gamma radiation, while is making those structures extremely heavy? suggestion: so currently you define volumes inside the ships, and structures to be "airtight" by air - that you have to check very very often during game, but with radiation you do something that is only similar - except not for "air blocks" but for blocks that do not contain lead(, or bismuth), and you do not check the "radiationtightness" as often as "airtightness" maybe against the "weaker radiations" the blocks are protective without the need of "radiationtightness" - so the weaker radiation is the current radiation mechanic with added "portable electromagnets" also i think bismuth should be higher tier than lead because the same amount of material is with bigger atomic radius - making it possible to build blocks that are smaller than the ones built with lead - so lead is for ba, and cv, while bismuth is for sv, and hv (bismuth is also the more rare material and with more mass) bismuth also looks nice in real life weaker, and gamma radiation sieverts are the same, but the player is notified about the type of radiation from a distance via the map maybe certain pois will also possess something in it that will radiate gamma radiation maybe certain entire star systems emit unusual gamma radiation - against which the player has to build parts of their cv, and ba out of lead fromt then on a block can either be armored against weapons (via titanium, and sathium (maybe)), or armored against radiation (via lead, and bismuth) - not both summary: by introducing the new type of "weaker radiation" (alfa, and beta radiations), the players can still be protected inside their vehicles without those built out of lead, and bismuth - and may even be able to craft the portable electromagnet that is going to protect them in a small area for fuel in the mean time gamma radiation is present in more difficult complete solar systems, near more difficult pois, and on more difficult planets - with some of the planets requiring the player to not use their cv built out of lead in its crushing atmosphere, but build their sv, and hv using bismuth (a more advanced material in place of lead - that can be used for "expected thinner walls" of radiation protection) - in the mean time players will still need to use lead for their cv, and ba in order to protect the crops inside, or the player inside, possibly "infantry" inside against gamma radiation (not against weaker radiation) in case of both ba, and cv lead will suffice against gamma radiation due to an "expected thicker wall thickness"
