New Zealand G/R.13 NOTE BY NEW ZEALAND Gives brief notes in reply to the questions contained in individual paragraphs of annexes to letter PO 131/224 of 9 April 1956 (Annexes derived from G/R.10). Other sections describe: measurements of radioactivity (only radon found) collected from air at Wellington by filter and by electrostatic precipitator February 1953 ~— May 1956, also by an impactor method in 1953 and in rain water on certain dates November 1955-—May 1956; results of measurements of total beta activities of fallout by sticky paper method May —July 1956. G/R.107 NEW ZEALAND REPORT TO U. N. SCIENTIFIC COMMITTEE ON ATOMIC RADIATION: EFFECTS OF ATOMIC RADIATION MEASURED IN NEW ZEALAND TO 31 JULY 1957 A set of notes on the current status of various programs in New Zealand within the field of interest of the Scientific Committee on the Effects of Atomic Radiation, including preliminary measurementof radioactive fallout, C' activity airborne, natural and artificial radioactivity, and occupational gonad exposures. G/R.185 LETTER OF DEPARTMENT OF HEALTH, DOMINION X-RAY AND RADIUM LABORATORY, CHRIST CHURCH, NEW ZEALAND Contains: (1) Description of radiation protection measures in New Zealand; (2) Results of routine monitoring of radiation workers; (3) Preliminary results of statistical study on genetically significant gonad dose from X-ray diagnosis. Norway G/R.14 REPORT OF 3 PARTS Suggests taurine biochemistry and lens opacities as biological indicators for low doses. Gives notes on disposal of small amounts of radioactive wastes. Describes and gives results of analyses by pot method in 1956 of total beta activity due to fallout on ground, in air, in drinking water, and accumulated in snow falls. Includes someanalyses for Sr*?, G/R.92 RADIOACTIVE FALLOUT IN NORWAY Contains information on methods and results of measurements of fallout in Norway. G/R.106 INFORMATION ON RADIOLOGICAL DATA Summarytables on radiological data in Norway with an extensive set of data on x-ray and natural radiation exposures. G/R.106 (Add.1) Correction to above report. G/R.111 ON THE DEPOSITION OF NUCLEAR BOMB DEBRIS IN RELATION TO AIR CONCENTRATION Studies the relation between the deposition of fallout and the airborne activity. It appears that in 1956-1957 the fallout in the Oslo area was roughly proportional to the product of precipitation and airborne activity at ground level. G/R.112 RADIOACTIVE FALLOUT IN NORWAY UP TO AUGUST 1957 Gives the results of measurement of fallout materials in air, precipitations, water, and other samples. Measurement of airborne activity at high altitudes are included. Sr® values are computed from total @ activity, a small number of samples having been checked by chemical analysis. Samples of water, milk, and urine have been analyzed for I'*!, G/R.113 RADIOCHEMICAL ANALYSIS OF FALLOUT IN NORWAY Describes the methods used in Norway for determination of Sr*°, Cs!8", and 143! and contains data of Sr®* and Cs" activities in water and milk and I! in milk, in the period February —June 1957. 186 RMS:
