The fundamental principle applied to the transport, storage or containment of radioactive material is that the protection comes from:
the distance underground that the sample is stored
the rating of the waste level on the outside of the container
the design and security of the packaging that encloses the radioactive matter
the speed at which the radioactive material is transported from the production facility to the storage facility

Liquid ammonia is produced at high temperatures and under great pressure in a tank by passing a mixture of nitrogen gas and hydrogen gas over an iron catalyst. the reaction is represented by the following equation. n2(g) + 3h2(g) → 2nh3(g) changing all but one experimental condition will affect the amount of ammonia produced. that condition is a) increasing the concentration of both reactants b) changing the temperature within the tank c) decreasing the pressure within the tank. d) increasing only the amount of nitrogen present.
