There are several possibilities I am aware of:
1) Pulse-chase labeling in vivo with tritiated uracil.
2) Measurement of RNA stability in the presence of Actinomycin D (I
think this works only for prokaryotes). Actinomycin D inhibits
the RNA polymerase, therefore if you measure RNA stability, you
measure RNA decay directly.
3) Nuclear run-off transcripts (I am not familiar with this one)
