Stratospheric fallout of bomb-produced cerium isotopes and atmospheric fractionation of nuclear debris [electronic resource]
Levels of Ce<sup>141</sup>, Ce<sup>143</sup> and Ce<sup>144</sup> in individual samples of rain and snow have been measured radiochemically at Fayetteville, Arkansas, during the past few years. The data are compared with the Sr<sup>89</sup>, Sr<sup&...

| 520 | 3 | |a Levels of Ce<sup>141</sup>, Ce<sup>143</sup> and Ce<sup>144</sup> in individual samples of rain and snow have been measured radiochemically at Fayetteville, Arkansas, during the past few years. The data are compared with the Sr<sup>89</sup>, Sr<sup>90</sup> and Ba<sup>140</sup> data also obtained at Fayetteville, Arkansas. The concentrations of both radiocerium and radiostrontium show a marked seasonal variation with a peak in the spring and a minimum in the fall. During a nuclear test suspension period, the Ce<sup>141</sup>/Ce<sup>144</sup> ratios in a series of rainfalls can be expressed as a simple function of the decay constants of Ce<sup>141</sup> and Ce<sup>144</sup> and the time elapsed since the cessation of the nuclear test series. The Sr<sup>89</sup> /Sr<sup>90</sup> ratio data, however, tend to deviate from such a theoretical equation and show a considerable scatter of experimental points. The Ce<sup>144</sup>/Sr<sup>90</sup> ratio data, on the other hand, can not be expressed as a simple function of the decay constants and time. These results are tentatively explained as due to the effects of fractionation of the bomb-produced fission products in the atmosphere. | |
