Cumulative fission yields of short-lived isotopes under natural-abundance-boron-carbide-moderated neutron spectrum

Ultrasensitive Sensor for Uranium Monitoring in Water Ecosystems

“…Different instrumental techniques enable uranium determination in environmental samples. Suitable techniques for this purpose are, for example inductively coupled plasma optical emission spectrometry (ICP-OES), 12,13 inductively coupled plasma optical emission spectrometry (ICP-MS), [14][15][16] spectrophotometry, 17,18 fluorometry, 19 gamma-ray spectroscopy 20 or accelerator mass spectrometry. 21 However, each of them has limitations which hamper their use, e.g.…”

Determination of 238U(n, γ) and 238U(n, f) reactions cross-section in the neutron emission spectrum of 241Am-Be source

“…( ) is the average fission yield of the product in the energy interval between E i and E i+1 . was calculated as Y 8 = 4.2 ± 0.3% based on data points taken from [47,48,50,[56][57][58][59]. There were few data concerning 238 U(n, f) 134 I and 235 U(n, f) 134 I which are related to the decay to 134 Te as an accumulative mass range.…”

“…Figure 6 illustrates the variation of the fission yield of143 Ce with neutron energy for 235 U(n, f) reaction (denoted Y 5 ) and for 238 U(n, f) reaction (denoted Y 8 ). Data points for 143 Ce in 235 U(n, f) reaction are from[43][44][45][46][47][48][49][50][51][52][53][54][55]. Data points for 238 U(n, f) reaction are from[47,48,50,51,[56][57][58][59].…”

“…Data points for 143 Ce in 235 U(n, f) reaction are from[43][44][45][46][47][48][49][50][51][52][53][54][55]. Data points for 238 U(n, f) reaction are from[47,48,50,51,[56][57][58][59]. The 241 AmBe averaged spectra were found = = 5.1 ± 0.4%, see table 3.…”

RAPID: The Development and Application of a Hybrid High Pressure Ion Chromatography and Inductively Coupled Plasma Mass Spectrometry Method for the Direct Analysis of Irradiated Materials

“…Due to the limited sample size, the analytical tools traditionally employed for fission product analysis are radio-analytical techniques, such as non-destructive gamma-ray spectroscopy [13][14][15], and neutron activation analysis [16]. Unfortunately, in such samples, spectral interferences and the need for background discrimination increase dramatically the closer to the time of irradiation the analysis occurs.…”
