Can't find radioactive ore

[MrBAG]

I completed all Danger In The Deep quest and spend +3 days finding at least 1 piece of this ore. And nothing. Only me have such problem?

Make sure you look for it on a day when the fortuneteller says you will have good luck. Otherwise, you may not find any, even if you use luck buffs to compensate. If you check the Stardew Valley Wiki, it will tell you that radioactive ore nodes are mostly dependent on daily luck.

Did you turn on the hardmode mines after completing the quest? Go to floor 120 and push the button. You won't find radioactive ore in the normal version of the mines.

Looks like one of the mod cause this issue.
I loaded normal SW (not SMAPI) and face a lot of radioactive ore

Dangerous Skull Caverns is better now if you have access to that.
