Radiation Sickness Guide

How the Casualties: Unknown radiation System Works

Casualties: Unknown radiation is not a cosmetic status bar; it is a delayed kill mechanic that keeps working after you leave the hot zone. If you are looking for a practical Casualties: Unknown radiation guide, the core rule is simple: avoid exposure first, treat early second, and never let a high dose trap you in full incapacitation. The system tracks your dose up to 30 Gy, and the higher it climbs, the more of your character’s basic functions it strangles—consciousness, immunity, happiness, brain health, muscle health, thirst, and sickness. This guide breaks down exposure sources, threshold effects, treatment math, and emergency escape tactics.

The dose counter is the number you need to watch. In Casualties: Unknown radiation, the health panel shows a value scaled from a 0–100 internal sickness track, with the displayed value equal to 0.3 times the internal number. That matters because the displayed dose is the number used in the effect formulas below. Once exposure begins, you are not waiting for one dramatic hit; you are managing a resource that decays slowly and punishes every extra second near a source.

Use that table as a proximity alarm. Spent fuel is the worst listed source, a barrel is only slightly less punishing, and rad water is a trap because the exposure continues for 45 seconds per consumption. If your route forces you near any of these, count the seconds and leave before the first severe moodle appears.

Thresholds, Moodles, and the Hidden Effect Stack

Casualties: Unknown radiation effects begin above 0 Gy. The severe radiation sickness stage appears above 15 Gy, and the final Chernobyl wannabe stage appears above 24 Gy. Higher stages inherit earlier effects and scale them instead of replacing them, so a high dose is not a new problem—it is every old problem getting worse. Radiation is capped at 30 Gy. High exposure also carries internal bleeding risk, which is why the dose counter is not just a mood debuff.

The radiation exposure thresholds matter because the underlying formulas scale continuously between stages. Consciousness is capped at 100 − (radiation × 2.333). Immunity is reduced by radiation × 1.67. Happiness drops by radiation divided by 3. Sickness rises toward radiation × 3.33, and if sickness passes 30, every limb takes skin damage. Brain health, muscle health, limb pain, and thirst also worsen as the dose rises.

The 6 Gy row is a useful reality check. It is not a “safe” dose just because it is far from the cap: consciousness is already down to 86%, immunity is down by roughly 10%, happiness is down by 2, sickness is climbing toward 20%, and several health and thirst meters are sliding in the wrong direction. Small numbers add up quickly in this system.

Treatment and Recovery: Anti-rad, Time, and Support

Casualties: Unknown radiation treatment is a race between removal and damage. Anti-rad is the most valuable option because it shortens recovery time sharply. Time alone removes 6 Gy per 10 minutes, which means a worst-case 30 Gy exposure can take about 50 minutes to clear without treatment. That is not a safe waiting period if your support stock is thin. Plan to treat before symptoms snowball.

Long recoveries are survival checks, not just dose checks. A steady supply of LRD serum, blood bags or IVs, disinfectant, immunity boosters, and drinks is needed to subsist through the worst-case window. Antiserum and chest drains are valuable contingency assets because radiation can lead to additional health issues such as hemothorax or sepsis. Do not start a decontamination run with an empty medical cabinet.

Geige-fruit deserves separate caution. A random swing of plus or minus 1.5 Gy is not a controlled treatment. If you are already near a threshold, the wrong roll can push you into a worse stage. Use it when the alternative is doing nothing, not as a planned replacement for Anti-rad.

High-Dose Escape: Stimulants, Ragdolling, and the 30 Gy Trap

In Casualties: Unknown radiation, the 30 Gy cap leaves consciousness at roughly 30%, right on the edge of incapacitation. Full incapacitation is a death sentence: you will never recover. The worst outcome is therefore not a high number by itself—it is a high number plus a lost movement window. Stimulants can create brief windows of increased consciousness. Use those windows to ragdoll away from the source, then repeat until you are out of range. Higher-grade stimulants make the timing easier. Medical-grade stimulants, exclusively, give enough consciousness to use a jetpack during those windows.

1. Do not wait for the moodle to max out. Move at the first sign of severe sickness.
2. Use the strongest stimulant you have before consciousness bottoms out.
3. Use each window to create distance, even if that means ragdolling in short, ugly bursts.
4. Save medical-grade stimulants for terrain that cannot be crossed by ragdolling; they are the only grade listed as enough for jetpack use.
5. Once outside the source range, start Anti-rad and work through the support checklist.

This is a desperation route, not a routine commute. It depends on having stimulants, a source you can actually leave, and enough health to survive the damage already done. Prevention remains stronger because it avoids the consciousness trap entirely. If you have a choice between grabbing one more container near spent fuel and leaving with a working dose, leave.

Prevention Checklist and Common Mistakes

In Casualties: Unknown radiation, prevention is more effective than treatment because every second near spent fuel or a barrel raises the dose you must later remove. The best radiation plan is a route plan: know where the hot zones are, keep your distance, and carry treatment for the moment a route goes wrong.

Common mistakes are easy to list and painful to survive:

• Chasing loot in a hot zone after the first severe moodle.
• Using Geige-fruit as a planned cure instead of a desperate gamble.
• Waiting until full incapacitation to use stimulants.
• Forgetting that immunity loss makes every other injury harder to manage.
• Entering a recovery period without Antiserum and chest drains as contingencies.
• Treating the 30 Gy cap as a target rather than a failure state.

FAQ

What is the maximum Casualties: Unknown radiation dose?
The cap is 30 Gy. At that level, consciousness is capped around 30%, which is the edge of incapacitation.

What are the most dangerous exposure sources?
Spent fuel is listed at up to +1.8 Gy/s, a barrel at up to +1.25 Gy/s, and rad water at +0.001 Gy/ml/s for 45 seconds per consumption. Spent fuel and barrels are the fast threats; rad water is the slow trap.

Does Anti-rad beat waiting out the dose?
Yes. Time removes 6 Gy per 10 minutes, so a worst-case 30 Gy exposure can take about 50 minutes to clear without treatment. Anti-rad is the most valuable treatment option because it sharply reduces that recovery window.

Can you survive full incapacitation at a high Casualties: Unknown radiation dose?
No. If incapacitation sets in, you will never recover. Stimulants can create brief windows of consciousness before that happens, allowing you to ragdoll out of range, but this is an emergency escape rather than a reliable plan.
