Discussion.

Atom, ATOMIC is more appropriate to the sign of radiation. Biohazard more of the topics about zombies and viruses. Stalker and the Isotope is generally not associated with this picture.
As Toxic as it is more just clinging to this picture, even though I don't know what it means, but what is acid green, I think the word fits.

Thanks for the opinion!
Just the couple of thoughts were:
Stalker has been associated with radiation, and radiation protection - gas mask(to a small extent, from dust mostly).
Isotope - also the radiation, in principle.

Venom:) This mask looks pretty dark, and poison greens are always painted, at least in games.

Toxic. The Association of the games - poison always green. )

Grass...

6. Toxic.
This Britney Spears singing.

There is nothing to discuss. Toxic. Or BioHazard, but it is rather cool from the movies than actually used the term.
And Toxic is not fully the correct term. Toxic substances are not always airborne. But you have chosen, this term is the closest.

The closest term that comes to my mind, this airborne contamination. Ie infection is transmitted by air.

Atoms and isotopes as well, and stalkers (you know, the game made the masks) there is no direct relationship to the masks do not have. The mask club (consisting of atoms, and even - isotopes) will not stop.
Of course, there is residual radiation. But here the more appropriate term airborne contamination.

Thank you! I just maybe with a picture even Maleh confused. Have in mind the masks at all. Not this picture exactly.

Masha
Ahah, yeah. In the Google pictures Britney appears immediately)))

Now to this what the terms are more appropriate?
1. Toxic.
2. Biohazard.
3. Stalker.
4. Atomik.
5. Isotope.
6. Crisis.
