Frequently asked questions

What are the four types of radiation in Isotope Decay Mod?
The four types are alpha particles (strong up close but easily stopped), beta particles (medium range), gamma and X-rays (highly penetrating), and neutrons (deep-penetrating).
How do you protect yourself from radiation in this mod?
You can wear a full hazmat suit for protection, use dense shielding blocks like lead and concrete, and take medical items like Iodine Pills, Prussian Blue, or Radaway to reduce exposure.
What happens when you carry radioactive items in your inventory?
Carrying dangerous items in your inventory or hotbar gives your character direct radiation exposure, which can cause screen static overlays and prolonged sickness.
How do you monitor your radiation exposure?
You can use a Geiger Counter, which clicks faster as radiation increases, or a dosimeter to track your total body dose.
What real-world isotopes are included in the mod?
The mod includes over 40 real isotopes such as Uranium, Plutonium, and Cesium that decay over time according to their real-world half-lives.
Can radioactive materials transform nearby blocks?
Yes, radioactive blocks and fluids can irradiate nearby blocks and slowly transform them over time, as shown with grass and leaf blocks.
