The Ontario Water Resources Commission in 1971 found that some lakes in j the uranium-mining area of El-1 hot Lake had concentrations of1 radium 226.200 times the back-1 ground level because of dump-1 ing The background el of radi- ation is the same cinujnt of radiation all mankind ha.s been subject to since Adam and Eve. There were faduies ot nu- clear plants releasing radio- actne substances into the air such as those at V.mdscale in Britain in 1957. the American reactor at Idaho Falls. Idaho, in and the Fermi reactor on Lake Erie near Detroit in 1966. There was waste heat from such plants causing tempera- ture increase in local watei- ways or in short-line regions near nuclear plants Finallv, there was the of "ni'i-'ear now v lUnn Ire gt of any j br ght lunatic "These are all rather extteme possibilities, but possibilities they are." said Dr Jones The panel was held after a morning session in which George Gathercole, chairman of Ontario Hydro, described the successful 2.000-megawatt reac- tor at nearby Pickering as "the flagship of the Canadian nu- clear program W M Camp of Atomic Energ> of Canada Ltd told how the federal atomic energy con- trol board licenses the disposal of all radioactive materials' trom the country s tour nuclsar power stations, the Nuclear Power Demonstrator on the Ot- tawa River, the plant at Douglas Point on Lake Huron, at Gentilly, Que and at Picker- ing- Only small amounts of radio- active gases and liquids vveie discharged into the air and wa- ter courses "in carefully mom- j tored quantities that are well below the permissible limits j Stored wastes with relatively short-lived radioactive isotopes and all solids were put away in an isolated place Spent fuel rods, whose ele- ments might take as long as a million years to decay into the low radioactivity of natural ura- nium, were dropped into water- lillsd receiving bays at the re- ac-lor until they could be safely buried or reprocessed for re- cycling for the plutonium in them. must always have at! least one acceptable storage Mr Camp said. "Fu- ture generations which will have to deal with our wastes undoubtedly will develop better methods than we have today, but we must bequeath them at least acceptable route which they can follow if they wish." One of the worries about nu- clear-energy plants has been the amount of heated water they discharge into waterways. For instance, the Pickering, Ont. plant works at 30-per-cent efficiency, meaning 70 per cent of the heat generated goes back into Lake Ontario in the cooling water. H. A. Clarke of the Ontario ministry of the en vironment had no conclusions to offer. He said "Although thermal discharges to the aquatic environment not known to be a problem in Ontario at thus time, available information is limited to ade- quately assess environmental effects and extensive studies are being conducted primarily by Ontario Hydro together with the ministries of the environ- ment'and natural resources." What it all meant was that if cooling water from thermal sta- tions was found to be doing any significant harm to the lakes, "Ontario Hydro has agreed that appropriate remedial measures will be implemented or in- corporated into future station design More Women are Saying I'M SURE SAVING PRICES EFFECTIVE in Lethbridge Stores June 20-23, 1973 SAVE ORANGE CRYSTALS MAC AND CHEESE EMPRESS Pkg. of 01. net wt. pkgs.
