Radiation refers to the effects of radioactive items and objects in the game, which cause damage to the pioneer unless a Hazmat Suit is worn. While Radiation is in effect, the screen will become slightly distorted, Geiger Counter noises will be heard and a radiation level bar will appear in the upper part of the screen.
Radioactive items and objects
Currently, there are twelve types of radioactive items in-game, with different amounts of radioactivity (internally referred to as ItemDecay):
|Uranium Pellet (obsolete)||7.5||750|
|Encased Uranium Cell||0.5||100|
|Uranium Fuel Rod||50||2500|
|Uranium Resource Node||10000||10000 per node|
|Uranium resource deposit||15 × Amount of Uranium contained (usually 54~66)||About 900 per deposit|
|Encased Plutonium Cell||120||24000|
|Plutonium Fuel Rod||250||12500|
All of the items listed above glow in the dark.
The formula for calculating the radiation level (intensity) is:
- Amount of items. So 2 stacks of Uranium counted as 200.
- Distance between the player and the item, in meters
- : Refer to the table above.
Radiation intensity for multiple radioactive sources, such as items in different containers, are summed scalar in 3D. After the summation, the intensity level is then capped between 0.2 (0.44% radiation damage) and 45 (100% radiation damage). A pioneer will not receive any damage below 0.2 intensity. Beyond 45, the radiation damage is capped, which at this intensity, kills the pioneer in 5 seconds or consumes the Iodine Infused Filter at a maximum rate of 1 per 12 seconds. In-between, the filter lasts longer as the radiation level reduces. The radiation bar in the game screen is capped at 26.7% radiation damage.
Items closer than 0.5 meters or in the inventory are counted as x = 0.5 meters
The above formula can be applied to the following situations:
- Items on the ground
- Items in vehicles, including trains, and even if the vehicle has fallen onto the bottom of the void
- Items in Storage Containers, Industrial Storage Containers and Personal Storage Box including the one in The HUB
- Items in Miners or other production buildings
- Items on Conveyor Belts
- Items in pioneer's Inventory/hand
- Items carried by a Lizard Doggo
- Items in Death Crate or Loot Box
Be careful when hand-mining Uranium ores, as Uranium in the inventory can kill the pioneer quickly, due to the short distance of x = 0.5 meter. Other creatures such as Stingers or Lizard Doggos do not take damage from Radiation.
In Tier 7, a Hazmat Suit can be unlocked via its respective milestone. Having the suit on won't stop the noises, but will protect the pioneer from Radiation damage. As the suit requires Alclad Aluminum Sheets to craft, it is required to complete the Bauxite Refinement milestone first.
Entering any vehicle also stops the pioneer from taking radiation damage.
Foundations, walls, terrain nor water don't reduce radiation levels by any means.
- Beware when disposing of radioactive items as it can currently cause a glitch, in which the area acts as if a dropped piece is still there.
- If keeping one or more Lizard Doggos, keep them in a containment pen with a conveyor system ready to handle the waste, in case one brings you Uranium Waste . Alternatively, kill the Lizard Doggo to delete the waste.
- An interactive map with a radiation overlay. It allows you to upload a save game and then displays the radiation map.
- Nuclear waste cannot be disposed of with the trash can in your inventory.
- There is a bug where after the pioneer mined some Uranium deposits (which is usually performed to remove their radiation), followed by deleting the Uranium in the inventory, the radiation effect persists and also continuously draining the Iodine Infused Filter. To reset the radiation, drop the Uranium (if any) from the inventory, run well away from it, save the game then reload.
- When radioactive material is stored in a Storage Container, the container may emit residual radiation after all radioactive materials have been removed. To eliminate this, dismantle the container.
