The nuclear generator on Apollo 13 got more attention because, of course, it ended up coming back to Earth rather than being left on the Moon. Mission directors were none too happy when some scientifically illiterate and overcautious politics necessitated them diverting time from their efforts to keep the crew alive to design a descent trajectory for the LM that would put the SNAP-27 generator in the deepest part of the pacific in order to avoid the risk of showering somewhere with plutonium: a risk that had already been mitigated right in the early design stages. The SNAP-27 generator was already designed with the possibility of unexpected re-entry or destruction of the launch vehicle in mind, so was highly unlikely to release plutonium anyway.
