![]() Typically, for a decay chain where the daughter is also produced (isomers) Simplifications have been made as indicated in the comments column in Remember, the X in EXP(X) is limited to |X|<709 ![]() This can beĬorrected by reformulation or approximations but has not been done. Precision is inadequate and you get negative results. Such as 0.1 μCi using: index.html?decay=0.1įor some numerical combinations with very large half-lives the numerical The cutoff level, or to 0.0005 μCi if cutoff is 0. The cutoff values for displaying activation data are set to 0.0005 μCiĬan be displayed using: index.html?cutoff=0 decay cutoff The activation calculator determines the amount of time for the activation to decay to Index.html?abundance=NIST activation cutoff The NIST database can be selected for isotope abundance using: Scattering calculator uses the NIST atomic weights and isotope compositionĬalculation parameters are controlled by URL: isotope abundance By default, theĪctivation calculator uses values from the IAEA Isotopes is used to determine the total activation. WhenĪn element is used in a formula, the natural abundance of the individual The neutron activation calculation follows ( Shleien 1998).Īctivation is a function of isotope, not element. ![]() Within the NCNR, you can access a list of This is only need for computing the neutronĪctivation from the experiment, and is not used for computing scatteringĬross sections. Provide the thermal flux equivalent for the pre-sample beam configurationįor the instrument. ![]()
