In Call of Duty: Warzone's DMZ mode, players can perform various tasks to earn money and other rewards. You can pick up and complete several types of contracts in Al Mazrah. One of these contracts is Secure Radioactive Material, one of the Tier 2 Legion Faction Missions called Buried Barrels.
How to locate the Secure Radioactive Material contract in DMZ
As shown in the image above, the Secure Nuclear Material contract is marked by the radiation or hazard symbol on the green radio. This contract spawns at random locations across the map and can be picked up to complete the Buried Barrels Legion Faction Mission.
How to complete the Secure Radioactive Material contract in DMZ
Once you pick up the contract, a cache location will be marked on your tactical map. You can reach this location using a vehicle or simply running to it. Clear out any AQ guards nearby and interact with the cache. Pick up the Geiger Counter from the box, and it'll be added to the tactical slot in your loadout. Now, a new location of the hidden nuclear stash will be marked on your map.
Enter the highlighted area and try to locate this stash using your Geiger Counter. The reading spikes when you are near the stash. Once you find the radioactive waste container, open it to pick up all the cash and other valuable items inside. Now find the second stash in the same way, using your Geiger Counter in the next marked area. Also, remember that you must pick up at least four items to complete the Buried Barrels Legion Mission.
