2.5. Included Examples

2.5.1. List of example projects

In most cases the associated literature for an example project is cited within the projects; see TAB “Procedure” after loading a project. See also Help topic “Used literature”.

All example project files can be considered as being evaluated, because they originate from associated publications, or they were confirmed by colleagues through independent intercomparison calculations.

Note

In 2023 and in 2024, all projects were checked with respect to the correct use of physical units. Only very few errors were found and corrected.

All example project files indicated by the \(\surd\) symbol in the left column can be considered as being evaluated, because they originate from associated publications, or they were confirmed by colleagues through independent intercomparison calculations.

2.5.1.5. Revision of physical units in the examples

With version 2.4.13 of UncertRadio an option was introduced for deriving the physical units of dependent quantities by calculations; see chapters 2.27, 2.26 and Section 5.21. In the context of applying this option, the units used in the example projects of section Section 2.5.1 were tested for correctness. Several modifications were found to be necessary. They mean, that not all units introduced earlier by the author of this program were correct or functional.

In some cases notes about the modifications were documented within the project file, TAB “Procedure”. In most of the cases, it was necessary to change the existing unit “1” (or “ “) for detection probability variables (often called eps…) to “1/Bq/s”. This helps the output variable to receive the unit part “Bq” instead of “1/s”. These latter changes were only seldom documented within the project files. In the example J-ALUFT-Sr-89-Sr-90_V2_EN.txp, two parameters, a and b, used for calculating eps2, got the new units “1/Bq/s/mg” and “1/Bq/s”, respectively.

In another case, Ra226_U235-at-186keV_EN.txp, the equation RRa = RS – RU5 resulted in a difference of the units “1/s” and “Bq”; in this case, in the program the first one was then applied as the unit name for RRa.

In the case of Ac228_binomial_V2_EN.txp, the detection probability epsD is used two times, as part of the parameter p, which should be dimensionless as a parameter of the binomial distribution, and as a part of the calibration factor. This dilemma was solved such that the epsD which is used within the expression for p, receives the unit “1” (or ” “), while a second variable epsD_U was introduced, which as part of the calibration factor got the unit “1/Bq/h”, but the measurement value was set equal to one (without uncertainty).

In such examples explicitly containing scaling factors of 60 for the unit “min” or 1/1000 for the unit “g”, two special switching variables (or Trigger variables) were attributed to these factors; see section Using switching variables in equations.

For a group of projects their version number (_Vx_) in the file name was increased:

  • Ac228_binomial_V2_EN.txp

  • DWD_sr89_sr90_TDCR_procedure_V2_EN.txp

  • Galpha_beta_Rusconi_2006_V2_EN.txp

  • J-ALUFT-Sr89-Sr-90_V2_EN.txp

  • Janszen-Sr-89-Sr-90_V3_EN.txp

  • Moreno-Sr90_IAEA-135_V2_EN.txp

  • sumEval_sum_V2_EN.txp

  • sumEval_mean_V2_EN.txp

  • vTI-Y90-16330_Blw_V2_EN.txp

  • vTI-Y90-16671_Blw_V2_EN.txp

  • vTI-Y90-16748_Blw_V2_EN.txp

A consequence of calculating units of dependent variables (withing the menu item “test physical units”) is the transformation to basic units. In some cases, the associated scaling factors change the output quantity value powers of 10:

Galpha_beta_Rusconi_2006_V2_EN.txp: factor 1000 (1/g 1/kg) (permanently changed)

Sterlinski-2008-NAA_EN.txp: factor 1.0E-9 (due to a unit “ng/g”)

sumEval_summe_V2_DE.txp: factor 1.0E+4 (1/cm2 1/m2)

sumEval_mitteln_V2_DE.txp: factor 1.0E+4 (1/cm2 1/m2)

The last three changes do not apply if the test of physical units is not used, i.e., if the program is used in the normal mode!
