scuba air tanks with mask like fire fighter use are better for nuclear dust then a NBC Mask that you got would not help any.

NBC suit and mask will not help any with dirty (nuclear dust) bomb go

the thing with nuclear bomb or dirty bomb once it get on you...dust lands on your body/clothing taken the radiation right into the body cells thats were the damage happens. lead suit is the only thing will help and that if it rated for high levels.

NBC mask can't stop gamma or xray from getting into your body...many think it will but its a joke to think that.

best thing you can do is wear a alert monitor patch/pen that will ether tell you the rads by color/scale rate or pen to alert you by.
