It is about {{convert|4|mi|spell=in}} long and marked by a slender glacier tongue feeding into it from the west. It was plotted by Australian National Antarctic Research Expeditions (ANARE) from air photos taken by the RAAF Antarctic Flight in 1956. The lake was named for Uwe Radok, Reader (head) of Meteorology Department at the University of Melbourne, who greatly assisted Australian National Antarctic Research Expeditions (ANARE)'s glaciological program.<ref>{{cite gnis|type=antarid|id=12299|name=Radok Lake|accessdate=2010-07-29}}</ref>

With a depth of {{convert|362|m}}, Radok Lake is the deepest known surface lake on the Antarctic continent<ref>[http://epic.awi.de/Publications/BerPolarforsch2003460.pdf The Expeditions Amery Oasis, East Antarctica, in 2001/02 and Taylor Valley, Southern Victoria Land, in 2002] {{webarchive|url=https://web.archive.org/web/20110724181052/http://epic.awi.de/Publications/BerPolarforsch2003460.pdf |date=2011-07-24 }}</ref> (whereas Lake Vostok is the continent's deepest subglacial lake) and the only known freshwater lake to host a floating ice tongue glacier (the Battye Glacier).<ref>{{Cite web |url=http://www.aad.gov.au/default.asp?casid=2565 |title=The Amery Oasis, Northern Prince Charles Mountains |access-date=2010-07-29 |archive-date=2009-09-30 |archive-url=https://web.archive.org/web/20090930182447/http://www.aad.gov.au/default.asp?casid=2565 |url-status=dead }}</ref> It is drained by {{convert|3|mi|km|adj=mid|-long|spell=in}} Pagodroma Gorge in to Beaver Lake.

Bainmedart Cove ({{Coord|70|51|S|68|3|E|source:GNIS}}) is a cove about {{convert|1|nmi|km|0}} long in eastern Radok Lake. The cove leads to the narrow Pagodroma Gorge. The name is a composite one made from the names of C. Bain, A. Medvecky, and J. Dart who spent a month at the cove studying the geology of the lakes area during the ANARE Prince Charles Mountains survey in January–February, 1969.

Pagodroma Gorge is a steep-sided gorge 3 mi long which joins Radok and Beaver Lakes. Photographed from ANARE aircraft in 1956. The gorge was traveled by A. Medvecky, ANARE geologist in January–February, 1969. Named by ANCA after the snow petrels (''Pagodroma nivea'') which nest in the weathered sandstone walls of the gorge.<ref>{{cite gnis|type=antarid|id=11274|name=Pagodroma Gorge|accessdate=2010-07-30}}</ref>

Glossopteris Gully ({{coord|70|51|S|68|6|E|source:GNIS}}) is a steep-sided, narrow gully on the east side of Bainmedart Cove. It was named by ANCA after the ''Glossopteris'' fossil plant found in the upper part of the gully.

Fossil Wood Point ({{coord|70|50|S|68|2|E|source:GNIS}}) is a point of land between Bainmedart Cove and Radok Lake. It was so named because deposits of fossil wood were found on the point.
