Note: A 0% reliable vehicle at the end of the phase counts as 1% reliable, there is no 100% anything in this game so do not worry about trying to build a x1% reliable vehicle to reduce down to 1% reliability using radiation.
The first mission for me with radiation was a request to orbit the moon, which should begin to appear after you complete the Lunar Orbit milestone in Era 1: Dawn of Spaceflight. I am certain there are more but I am writing the guides as I unlock the achievements at this time.
Radiation is similar to heat in that it accumulates at the end of each turn and can be used as an input resource to mitigate the negative effect. Unlike heat that ends the mission if it exceeds the limit at end of turn, radiation reduces your payload reliability by 5% to 10% for each unit of radiation.
Because each mission is somewhat random there is no way to provide a guide for every possible situation but the basic idea should be sufficient. Some missions may also not be ideal due to the low amount of radiation being gained each turn and the lower negative impact of each unit, and the overall requirement of the mission, so if you don't think the mission may work, the eventual next one may be better.
When you are in the phase of the mission with radiation, try and figure out which of the objective resources can be fully obtained in the first turn, which resources can be fully obtained on the last turn, regenerate power in the middle turns, and use that power to overcome the negative event from 1% reliability on the final turn to complete the objective and/or bonus objective.
For example, when I got the achievement I needed 4 communications and 4 observations for the bonus objective and started with 4 radiation on a 90% effective payload vehicle. I used 3 radiation and some energy to generate communication and turned the communications into 6 observations. Before I did anything I saw that I could turn 1 observation into 2 communications so I got knew I could meet the bonus objective at the end with my plan. After the turn I took 10% radiation damage to 80% reliability and gained 4 more radiation. Turn 2 I regenerated power for all my turns, gained 4 more radiation for 5 total that then reduced reliability down to 30%. Turn 3 I again regenerated power for all my turns, gained 4 more radiation for 9 total and reliability was down to 0% which effectively is the 1% required for the achievement. On the final turn, turn 4 I converted my 2 observations into 4 communication using 1 power from my reserve on each action to overcome the negative event and hit the bonus objective. The achievement popped as soon as the phase was complete and the summary result screen completed.
Per the tutorial, radiation can occur in stages that are not the final stage, but I would assume the achievement would also pop when that stage success screen appeared if done correctly.
