Following nuclear weapons tests, some WB-29s would use air sampling scoops to test radiation levels.

Because a day care center is next door, they are conducting air sampling and soil tests.

Example is the WC-135, a transport modified with special equipment for air sampling.

We repeated this procedure for the two air samplings using their respective means.

That's why there's such a thorough demand on every job and requirements for constant air sampling.

Fourpeaked also continued to vent volcanic gases at the same rate as revealed in earlier air sampling.
