It is a self contained residential area with _ Community Centre , Golf course and other forms of Retreat it. Workers ten thousand acres of land at Chalk River were acquired by the government for its project. About people work there More than 500 of whom Are scientific and technical personnel. The detailed research work involved in the project staggers the imagination of the Layman. For example one researcher has been at work for three years and is still at work seeking to exact Angle at which tiny particles known As neutrinos Fly. Off when an atom of uranium is split. There Are problems of Engineer no design. Problems involved in manufacturing new exact instruments designed and built in the shops at Chalk River. General manager of the project is j. L. Gray b.sc., ., a graduate of the University of Saskatchewan. Practically All universities in Canada have representatives in project. For example in the pro Cess and development Branch in the Industrial operations Section w. R. Livingston b.sc., Of the University of Manitoba is listed. The work of the process and development Branch consists of Many varied problems coming from any Branch in the Plant. They May involve development of methods of analyses or adaptation of existing methods improvements in or development of new chemical extrac Ion processes or methods for Fis Sion product separations. The design of new equipment particularly that necessary for re control operations is a con inning problem. A considerable amount of spectrographic analysis and mass spectrometer analysis is carried out involving the use of special techniques. In the near future a spectrographic Laboratory vill be established. Threads of Quartz newsmen during their tour were Hown an instrument which melts Quartz imported from the u.k., and spins it into a Fibre Only one four thousands of an Inch in Dia meter. The fibres Are then used to make super delicate Micro bal ances. So Fine Are the threads that ail that can be seen is the refraction of Light from them at certain angles. Just As impressive were the Micro balances themselves. These delicate instruments can measure Down to one Twenty eight Hundred Millionth of an ounce. With one of these instruments it would be pos sible to weigh the Dot made by a Lead Pencil on a piece of paper. These delicate instruments Are made in the project s own machine this is an artist s sketch showing a patient being treated in the newest Model of the co therapy unit produced by the commercial products division of atomic Energy of Canada limited. The first unit of this Model will be shipped to the Francis Delafield Hospital Iri new York in March. The source of Gamma rays which Are used for cancer treatment is the radioactive isotope Cobalt-60 which is produced in the Nix reactor at Chalk River. No other re actor is capable of producing Cobalt-60 with As High a specific activity is the number of Gamma rays per Gram of material As can be produced in Nix. Irradiation is returned for process ing recovery or separation of the desired isotope and after analysis shipped to the distributor. The Branch is also engaged in these shop. The the most equipment control laboratories possess up to Date and use Laboratory the latest methods of chemical analysis. The present trend is towards Micro analysis. The Range of analyses run from work on the constituents of stainless steel through mass spectrometer work to the electronic count ing of radioactive sources the chemical extraction Branch personnel handle radioactive materials which Are products from irradiation in the heavy water piles. The isotope production Branch is engaged in the production of radioactive isotopes. Material after Parathion of the useful fission pro ducts from radioactive Wates. Cobalt bombs among the better known products of the Chalk River operations is Cobalt-60, known As the Cobalt bomb used in the treatment of cancer in the beam therapy unit Chalk River produces More than 80 different kinds of radioactive isotopes. Half a dozen Cobalt-60 sources for cancer therapy have been made. One is scheduled for Winnipeg others Haye gone to hospitals in London ont Van Couver and new York. Saskatoon also has a Cobalt-60 unit for cancer treatment. Radioactive isotopes for use with in the human body Are turned out by the project. Radioactive isotopes now have wide application to Industry medi Cine agriculture and general re of various kinds. They May be used for example to detect flaws in castings or in welded objects. Iridium-192 is used to in Spect welds in tanks and pipe lines. Radioactive sources allow a quicker Job to be done and make it pos sible to Check welds in places where an a Ray machine could not be used. The High Neutron flux in the Nix pile makes it possible to produce some isotopes with a higher specific activity than can be produced elsewhere. Nutrition Cycle the nutrition Cycle in fresh water lakes is being studied with the Aid of radioactive phosphorous. Radioactive isotopes Are being used to determine the extent of Cor fusion in piers in Canadian har Dors. Others Are used in the Auto motive Industry the paper making Industry and the Oil Industry. The isotopes which Are mainly radioactive isotopes Are made by enclosing a Quantity of an appropriate substance in very pure form in a capsule which is placed in the Nix reactor. There some of the atoms of the substance Are trans muted by Neutron bombardment into the desired isotope. Rail rate of return by Shane Mackay Ottawa special c. D Shepard counsel for the Manitoba government suggested Friday the rate of return concept for railway business impractical. He made the suggestion to the transport Board hearing an application by the Canadian Pacific railway for a guaranteed 6.5 Pei cent return on its net investment in railway properties. Or. Shepard was Cross examining d. H. L. Purdy research director of the British Columbia electric corporation appearing As a witness or the cup who said the Prin Ciple had never been tried in can Ada. The Mere fact that United tales railroads As a whole have not been Able to earn a fixed rate of return does t mean that it is not practicable or. Purdy added. Commerce commission the . Interstate Commerce commission was instructed by con Gress in 1920 to fix freight rates at a level which would bring the rail Vays an average return of 5.5 per ent. The order expired in 1922 liter having failed to bring about he desired return but the Longres ional instructions remained on . Statutes until 1933. Or. Purdy suggested the statute iad Only been modified in 1933. Or. Shepard replied that the mod Tica Tion amounted to repeal of he rate of return principle in . Ailway Law. The Manitoba counsel also noted that the Turgeon Royal commission n transportation had reviewed the . Experience with rate bases and letter in . Law. He was Cross examining another car witness prof. Sidney Miller University of Pittsburg transportation economist is that right if the fixing of a fair rate of return is in the Law of the United states today it is a dead letter be cause of the subsequent actions of the interstate Commerce com Mission. Is that Well i would say that it is not explicitly in the statute As it was in the act of prof. Miller plied. Well of course that is what i would or. Macpherson said but if it is still by inference if it is still there by inference it is a dead letter in operation and has been for 30 Long that is prof. Miller confirmed. The transport Board s hearings on the application which began ast november will continue next the eight Western and maritime provinces which have opposed the Case will bring in sup porting witnesses and offer their counter arguments.

The agreement which expires full 31 this year will come up or renewal at a meeting in Washington Jan. 30. Many Prairie Arm organizations previously have indicated that they favor renewal Vith higher floor and ceiling prices. Delegates representing the Mani Oba Alberta British Columbia and Saskatchewan federations of Agri culture were in attendance.

By Rhoda Koven Don t ask me ask or that was the bitter answer a representative of the South korean Republic to a ques Tion on the War now ravaging his country. Yongho Chin director of land transportation ministry of transportation Korea is touring Canadian cities to study the Railroad Industry and its operations. He said that More than 20 per cent of South Korea s rail roads had been damaged by War but most of them were now either permanently or temporarily repaired. At pre sent nothing obstructs military transportation to the front. Shortage of material there is difficulty due to the shortage of materials needed to make repairs. Raiding bands of guerrillas hide out in the mountains during the Day at tacking farms and villages at night and dynamite no railways. This has meant that casual ties Are Leigh among Railroad employees. But the men have remained on the Job anyway so that operations out of Fusan have not been halted. Or. That the most important thing to remember was that the North koreans belong to the same race speak the same blood flowing through the same blood flowing from their veins As the South koreans. I believe that 95 per cent of the North korean people Are against communism. This will be an important Factor in ending the War. Even the Korth korean soldiers Don t like fighting but if they try to escape from the front there Are russian officers at the rear to prevent them. This is not a War Between. North and South Korea but a War Between two ideologies democracy and or. Chin began his tour of the country in Ottawa on oct. 17, and has already visited Montreal Moncton and fort William. He was greatly impressed by the vastness of the country and the generous Way in which its people have treated him. Or.
