Here's a British War Office document that published grenade test results.
Of particular interest in the difference between the UK No.36 defensive grenade with baratol filler, and the US MkII defensive grenade with EC filler (more stable but less powerful than TNT).
Pity they didn't also test the F-1, but the F-1 did use TNT.
This document also makes you wonder what criteria various sources use for 'effective radius'.
