Table 31b—CESIUM-137 DETERMINATIONSIN MILK, 1957-1958 (Measured at the Los Alamos Scientific Laboratory) . ——— Coding for 1957-1958 Milk Samples The 1957~1958 milk samples are tabulated by states and then In order of date of measutement. The columns are as follows: serial —o 1, Serial number 22000: 2. Subject code and date of measurement 4. «" specific activity measured in gamma rays per second per pound §, Cs/K gammaratio 22000: 22.000: 22000: Note: In all the tabulations, the K™ calculation is based on the assumption that this is the only nuclide counting in this 22000: channel, During periods of weapons testing, abnormal values of potassium are due to the presence of Ba-La-140, E 22000. Additional calculation is necessary to establish the true barium and cesium levels at these times, The machine program is being rewritten to accomplish this, The Cs/K gamma ratio can be converted to micromicrocuries of : 22000: 22000 cesium per gram of potassium by multiplying by 95, SubSerial No. ject code Potassium Date ¥ y " Sub- ratio, Serial No. dis/sec/lb Csa/K Control Potassium ject code Date _ y 22000 22000 Y ratio, 22000 26.243 0.0008 ae 28.286 35.776 0.0170 0.0975 a 2 dis/sec/Ib Cs/K 2200046450 1999 4/25/57 2100064050 3130 3/15/56 2100064050 3653 7/17/57 26.958 25.732 0.1620; 0.1600. 2200049850 1999 5/6/57 2200050150 1999 5/9/57 27.833 26.696 2100064050 3653 10/28/57 26.256 0.1653 2200108850 1999 11/21/57 26.322 0.0314 2200 26.713 0.1774 27,460 0.0520 2200 2100064050 2200064050 3653 7/19/57 3663 7/24/57 2100064050 3653 11/1/57 2100064050 3653 11/23/57 2100064050 3653 11/13/57 2100064050 2100064050 2100084050 2100084050 2100064050 2100064050 2100064050 3653 11/26/57 3653 11/28/57 3653 3653 3653 3653 3653 12/2/57 12/11/57 12/18/57 12/23/57 12/26/57 2100064050 3653 12/27/57 2100064050 2100084050 2100064050 2100064050 3653 1/4/58 3653 1/7/58 3653 1/10/58 3683 1/14/88 27.760 27.402 26.662 26.743 27.109 26.674 23,006 26.711 26,806 27.166 26.613 26.866 27.153 97.085 27.189 28.934 0.1676 0.1756 0.2114 0.1731 0.1672 0.1675 0.1716 3653 2/10/58 3653 2/15/58 3653 2/15/58 27.070 26.789 26.789 0.1906 0.1689 0.1689 26.711 0.1793 2100064000 3653 3/8/58 2100064000 $668 3/16/58 2100064000 9668 4/3/58 2100064000 $653 4/9/58 Glendale, Ariz. 1999 12/19/57 1999 12/27/57 2200122150 2200124550 2200126250 2200126950 2200131550 1999 1999 1999 1999 1999 2200134550 1999 2/20/58 1/3/58 1/9/58 1/15/58 1/24/58 1/30/58 26.166 28.732 27.865 27.652 0.0524 2200142673 1999 3/14/58 2200147173 1999 3/27/58 27.290 28.324 1999 3/6/58 2200149473 1999 4/3/58 0.0825 0.0572 28.085 27.785 27.188 27.621 29.326 0.0548 0.0481 0.0732 0.0291 0.0469 0.0478 0,0509 oOssecn 3130 vaeien osaa 4088 27,049 2200062650 3130 6/20/87 23.886 0.4676 . 20.514 0.2567 20.788 0.2778 2200053550 3130 5/10/57 0.1542 27.000 0.1804 26.766 0.2027 0.1912 1999 1999 1999 1999 3/8/57 3/14/87 3/22/57 4/3/57 28.497 29.891 28.452 27.042 0.0247 0.0433 0.0045 0.0056 2200042550 2200045150 1999 4/11/57 1999 4/19/57 27.322 27.054 0.0160 0.0254 27,859 2200 2200 2200 2200 : oC 390( 2201 2201 | 2204 220! 220: 220 | 220 220 220 ' 220 920 701 Fernsbridge, Calif. 26.751 0.1931 26.557 22,00 0.0804 0.0874 0.0383 0.0567 0.0067 0.0402 27.696 5700 3200! 0.0646 27.463 28.432 28.066 27.880 27.920 2200134850 1999 2/6/58 2200138800 1999 2/27/58 2200141373 0.1827 2200032750 2200033050 2200035750 2200038250 2200040450 1999 4/5/57 1999 12/12/57 2200132650 1999 2/13/58 2100064050 2100064050 2100064050 2100064050 3653 3/2/58 2200114950 0.1768 0.3321 0.1854 0.1772 0.1786 0.1815 0,1595 2100064050 3653 2/23/58 1999 11/29/57 2200115050 2200117750 27.091 26.851 2200111650 0.2016 0.2095 3653 1/28/58 3653 2/4/58 1999 11/7/57 1999 11/14/57 2200110350 1999 12/5/57 0.1814 2100064050 2100064050 2200102850 2200106050 0.0238 0.0076 2200072850 3130 7/23/57 2200079250 3130 8/22/57 2200086650 3130 9/25/87 2200119450 3130 12/30/57 2200125450 3130 1/21/58 2200143365 3130 3/17/58 14.057 21.180 24,090 0.3092 0.4202 0.6585 22.829 23.260 0.1652 0.1245 Fresno, Calif. 14 21.026 0.1180 21.368 0.1346 21.288 2200030750 3130 2/21/57 2200032050 3130 3/8/57 22( on 22 0.4447 2200103350 3130 57 2200107450 3130 11/22/57 0.0086 24.892 : 0.2807 0 22( | oo oD 22 22 22 : 22 2 2
