# Delta Force AZ3 Radiation Survival: Decontamination Chamber & Vehicle Locations > Where to find all 12 AZ3 decontamination chambers and 6 decontamination vehicle spawns, how to read the in-raid radiation HUD, and what to expect from the Haavk Purification Soldiers guarding contamination zones. - **Game:** Delta Force - **Category:** Maps & Loot - **Author:** LongBeam (https://guides-factory.com/about) - **Difficulty:** Beginner - **Reading time:** 8 min - **Published:** 2026-08-26 - **Updated:** 2026-08-31 - **Adapted from:** [All Decontamination Chamber & Vehicle Locations in AZ3 Power Plant Map | Delta Force Season 10](https://www.youtube.com/watch?v=1jOj-WH5aWw) - **Canonical URL:** https://guides-factory.com/guides/delta-force-az3-radiation-survival-decontamination-chamber-vehicle-locations --- ## 🎯 The core idea > AZ3's radiation isn't survived by gear alone — it's survived by knowing where the 12 decontamination chambers and 6 decontamination vehicles actually are, since neither shows up on your main map until you're standing close to one. This guide maps what each looks like, how to use them, and what else is roaming the contamination zones with you. ## Decontamination chambers don't appear until you're already close ![Delta Force AZ3 map overview legend showing the Contamination Zone marker among other map icons](https://api.guides-factory.com/media/uploads/2026/08/frame_0010_VNRSNrt.jpg) AZ3's full map overview marks Contamination Zones with a distinct icon (shown in the in-game legend), but the 12 individual decontamination chamber structures themselves are not pre-marked on that overview — they only appear on your mini-map once you physically approach one. That makes AZ3 one of the few maps where "knowing the map" and "knowing where the chambers are" are two separate kinds of knowledge; you can have memorized the whole layout and still walk past a chamber with no on-screen warning until you're within range. ![A yellow decontamination chamber tent structure beside a HAAVK-branded tanker truck on AZ3](https://api.guides-factory.com/media/uploads/2026/08/frame_0005.jpg) Visually, a chamber is a small yellow tent-like booth, usually sat beside industrial infrastructure (tanker trucks, generators, or warehouse walls) rather than out in the open — which is part of why they're easy to miss on a first pass through an area.

## What a chamber looks like once you're inside its radius ![Approaching a decontamination chamber on AZ3, marked with a green diamond and 35 meter distance readout](https://api.guides-factory.com/media/uploads/2026/08/frame_0060.jpg) Once you're within roughly 35 meters, the chamber renders on your mini-map and HUD with a green diamond marker and a live distance counter, letting you walk it down precisely rather than guessing. This particular chamber sits at the corner of a warehouse building, tucked behind stacked containers — a typical placement pattern the video repeats across all 12 locations: chambers cluster near buildings and industrial clutter rather than open ground. ## Reading the radiation HUD in a contamination zone ![A player standing in an active AZ3 contamination zone with an on-screen nuclear leakage warning and radiation status icons](https://api.guides-factory.com/media/uploads/2026/08/frame_0090_od9SIBV.jpg) Stepping into an active contamination zone triggers a visible warning banner ("Emergency Alert: Nuclear Leakage") on nearby signage, and the HUD adds a row of small status icons (a mask/hazard icon among them) alongside a percentage readout in the bottom corner. Across the raid this percentage moved between roughly 43% and 97% depending on how long the player had been in or out of a radiated area, which is consistent with it tracking [radiation](/guides/delta-force-az3-nuclear-power-plant-map-guide-radiation-extracts-keycards) exposure or remaining tolerance in real time rather than being a fixed value.

The video never explains this percentage number directly in narration — it's read here from the HUD across multiple points in the footage. Treat it as "a live radiation-exposure indicator exists and is worth watching," not as a precisely defined mechanic; the exact drain rate and damage thresholds aren't covered by this source.

## Interacting with radiation equipment: it isn't always instant ![A HAAVK-branded radiation control console reading "You pressed too fast, try again later" during a raid on AZ3](https://api.guides-factory.com/media/uploads/2026/08/frame_0100.jpg) Some radiation-related equipment on AZ3 — this console is labeled "RADIATION CBK 07" with a radar-style readout — has a built-in cooldown: pressing its interact prompt too quickly returns a "You pressed too fast. Try again later" message rather than activating. If you hit this message, back off and retry after a pause rather than repeatedly mashing the interact key, which won't shortcut the cooldown. ## Decontamination vehicles: six spawns, fixed patrol routes ![A white decontamination vehicle parked near a depot gate on AZ3, matching one of six fixed vehicle spawns](https://api.guides-factory.com/media/uploads/2026/08/frame_0110_nnohn2l.jpg) Separately from the 12 static chambers, six decontamination vehicles spawn and patrol AZ3 on fixed routes between specific areas — the creator's own testing across multiple days found each vehicle sticking to the same loop rather than roaming randomly, which means a route memorized once should hold up on future raids (barring a patch changing it). You can commandeer one by walking up behind it and holding the interact prompt (F), which lets you travel across the map faster than on foot.
The video's creator is still validating exact routes and openly asks viewers to report any vehicle spotted off its expected path — treat the routes as strong, tested leads rather than guaranteed fixed law, and expect the creator's companion map (linked from their Discord) to be the more current source if routes shift.
## Haavk Purification Soldiers guard some radiation areas ![Killing a Haavk Purification Soldier near a decontamination vehicle and an active radiation zone marker on AZ3](https://api.guides-factory.com/media/uploads/2026/08/frame_0150_XLOqCN6.jpg) AZ3 populates some contamination areas with an AI faction identified on-kill as "Haavk Purification Soldiers" — armed NPCs found patrolling near decon vehicles and chamber areas. The video's creator has found six possible spawn points for these soldiers but says explicitly they suspect there are more and haven't finished confirming the full list, planning a dedicated follow-up video once that's done. Expect armed resistance near radiation infrastructure, not just an environmental hazard.

## How this guide was fact-checked Chamber and vehicle mechanics (mini-map-only rendering, the 35m proximity marker, vehicle commandeering via F, fixed patrol routes) are read directly from Dash's on-screen footage and narration (2:54, published 2026-07-02). The radiation exposure percentage, the "RADIATION CBK 07" console and its cooldown message, and the "Haavk Purification Soldier" identification are all read directly from captured frames, since the video's narration is sparse and mostly describes what to look at rather than explaining every HUD element out loud. This is deliberately an in-raid, AZ3-specific guide — per the source video's own scope, AZ3's Black Site base-upgrade tree (a separate, long-standing progression system that Meltdown extended with a Decontamination Chamber upgrade raising radiation tolerance) is a different mechanic covered by written patch notes, not this video, and is out of scope here. ## What this guide doesn't answer This guide does not give exact radiation damage numbers, drain-per-second rates, or tolerance thresholds — the source video doesn't state them, and the HUD percentage observed in frames is reported here as an indicator that exists, not a fully explained formula. It doesn't cover the Black Site Decontamination Chamber base upgrade (the separate meta-progression system at Operations Level 9/14/27 that raises baseline radiation tolerance across raids) — that's a different system from the in-raid chambers and vehicles covered here. It also can't give you a complete, confirmed list of Haavk Purification Soldier spawn points: the video's own creator has only verified six and says more likely exist, with a dedicated follow-up video planned once that count is finalized. And if you've seen these chambers called a "shower room" elsewhere, that's not the term this video uses — on-screen and in narration they're only ever called decontamination chambers. --- ## FAQ ### Do AZ3's decontamination chambers show up on the main map in Delta Force? No. The main map overview only marks the general Contamination Zone, not the 12 individual chamber locations. Each chamber only renders on your mini-map, with a distance readout, once you're within roughly 35 meters of it — you can know the whole map layout and still walk past one with no warning. ### How many decontamination vehicles are on AZ3, and how do I use one? Six decontamination vehicles spawn and patrol AZ3 on fixed routes between specific areas, based on the source creator's multi-day testing. Walk up behind one and hold the interact prompt (F) to commandeer it, which lets you cross the map faster than on foot. ### Who are the Haavk Purification Soldiers in Delta Force AZ3? They're an armed AI faction found patrolling near decontamination vehicles and chambers on AZ3, confirmed by the on-kill nameplate 'Haavk Purification Soldier'. The source video has verified six possible spawn points but suspects more exist and hasn't finished confirming the full list, so approach radiation infrastructure expecting armed resistance, not just an environmental hazard. ### Is the Black Site Decontamination Chamber upgrade the same as the AZ3 in-raid decontamination chambers? No, they're two separate systems. Black Site's Decontamination Chamber is a base-upgrade in the long-standing meta-progression tree (unlocked around Operations Level 9/14/27) that raises your baseline radiation tolerance across all raids. The chambers and vehicles in this guide are in-raid, AZ3-specific structures you interact with during a single raid — different mechanic, different system. ### What does the radiation percentage in the AZ3 HUD mean? A percentage readout appears in the HUD alongside mask/hazard icons whenever you're near or inside a contamination zone, and it visibly moves (observed between roughly 43% and 97% across one raid) based on time spent in radiated areas. The source video doesn't explain the exact formula, so treat it as a live exposure indicator worth watching rather than a fully documented mechanic.
