It was built at the Manseau Shipyards, then disassembled and shipped by railroad to Waterways.[3] The Radium Queen was shipped first, and reassembled at Waterways, so she could tow the parts to assemble the Radium King downstream to the rapids on the Slave River. The parts to the Radium King were then portaged around the rapids to be assembled on the lower reaches.
In 2005 Atomic Energy of Canada published a study of the toxic legacy of the mining of radioactive ore at Port Radium.[4] According to the report all but one of the surviving vessels of the Radium Line were found to be free of contamination, with the exception of the Radium Gilbert, but whether the Radium Queen had been contaminated could not be determined, as she had been scrapped.[5]

Ships were used along the NTR to move barges loaded with uranium ore and concentrates (among other materials and supplies). Some vessels also transported cargo on board. Fifteen Radium Series vessels used along the NTR were identified in SENES (1994). Three were determined to have been scrapped, and the disposition of one, the Radium Cruiser, was unknown. Radiological investigations were conducted on the other eleven vessels. Only one, the Radium Gilbert, showed any evidence of contamination.
