Each icon shows how many of that explosive clear one blocker, cheapest first; the number under it is the sulfur to craft them. 40mm HE grenades come only from loot. 1 C4 clears any blocker, and a pickaxe mines one for its metal. Monument blockers lists every explosive and what each gives.

Underwater Lab radiation
no protection worn| Zone | Tier | Radius (m) | Centre (rads/s) | Half radius (rads/s) | Protection to block |
|---|---|---|---|---|---|
| 1 | high | 3 | 51 | - | max (1/s gets through) |
| 2 | high | 3 | 51 | - | max (1/s gets through) |
| 3 | high | 3 | 51 | - | max (1/s gets through) |
| 4 | high | 3 | 51 | - | max (1/s gets through) |

Rads per second. Your radiation protection subtracts from these, and the game caps protection at 50, so a zone above 50 always lets some through. What to wear names the gear that blocks it, and the radiation guide compares every monument.
What to wear
50% protection is the most that counts- Strongest zone
- 51 rads a second with nothing on. The game counts 50% protection at most, so 1 rad a second always gets through here, whatever you wear.
- Lightest that is enough
- Hazmat Suit50%Slot: whole body. Craft at workbench level 2. 1 rad a second still gets through.
- Cheap full kit
39% in all. Common or uncommon clothes made at workbench level 1 or lower. 12 rads a second still get through.
- Pills
- Anti-Radiation Pills take 75 off the radiation you have taken in, and 5 off your hydration. Use them for what still gets through.

Rads through is the dose at the strongest spot of the strongest zone with only that piece worn, the same figure as on the piece's own page. Pieces under 10% protection, the strongest zone of the weakest monument, are left out, as they are on the attire pages.

What opening every crate and barrel above once gives, on average, most first. The figures are the ones on each item's own page. Blueprints are not counted. Not counted, because no loot table was tested for them yet: Tech Parts Crate (3), Tech Parts Crate II (3), Vehicle Parts Crate (1). A full clear gives a little more than shown.
Underwater Lab spawns and respawn times
most alive at once| Spawns | Max at once | Per respawn | Respawn |
|---|---|---|---|
Crate50% | 1 | 1 | 15 to 30 min |
| 2 | 1 | 20 to 30 min | |
| 2 | - | no respawn timer |
A row with several items fills each spot with one of them at the odds shown. A timed row starts with one respawn's worth and adds that many each respawn until it reaches the max. Respawn times hold up to 150 players online; more players make them faster. Rows with no respawn timer fill once when the monument loads.
Methodology
Tested in game on live 4000 maps on our own server: loot containers by type (the average of 2 placed copies; containers spawn at random points, so a map can have a few more or fewer), recyclers, workbenches, research tables, repair benches, keycard readers and their tier, pickups inside the monument area, fuse boxes, NPC capacity, radiation per second and every spawner's limit and respawn time. NPCs are the monument's own guards; tunnel dwellers in a train station below and roadside scientists are not counted. No-building areas, Chinook drop zones, crash sites, train tunnel links and puzzle wiring were tested the same way. Scrap estimates use the measured average scrap per opening of each container type; a container not yet tested counts its guaranteed scrap, marked +. What you find here is each container count times the tested chance and average amount of every item in it, the same figures as the item pages. What to wear takes the protection of each piece off the strongest zone, the same figures as the attire pages. Tested on the current version of Rust.

loot containersUnderwater Lab: common questions
- What loot is at Underwater Lab in Rust?
- About 47 loot containers on spawn, the most common are Crate (12), Military Crate (7), Medical Crate (5). Opening all of them once gives at least 227 scrap.
- What keycard do you need at Underwater Lab?
- Underwater Lab has 4 Green keycard readers, 3 Blue keycard readers, 1 Red keycard reader, 4 fuse boxes. Bring a green keycard, a blue keycard and a red keycard.
- How much radiation is at Underwater Lab?
