Nope. At least, it wouldn't help in the nasty parts. The first couple of robots they sent in saw up to 650 Sieverts/hr [1] (about 650 Grays/hr, or 650 Joules/kg/hr) [2]. It started to kill the video and other controls so they pulled them after a couple of hours. It's not just sensitive processors; all the electronics is affected. A 2018 IOP paper [3] shows the tolerence of recent robots. The best could handle 1000 Grays total.

[2] A Sievert is the biological damage caused by 1 Gray, with adjustments for radiation type. A gray is one joule of radiation absorbed per kg.
