SIMS
The SIMS has been developed for algorithm response
simulation for RAMSYS measurement channel.
This software is a powerful tool designed to provide a
measurement channel/algorithm combination:
• The evolution of measurement conditions over time
(activity concentrations, dose rate,  ow rate, etc.)
• The measurement channel detection assembly (de-
tection ef ciencies, sensitivities to electronic noise
and nuclear backgrounds, etc.)
• The evolution over time of the measurements for
a channel/algorithm combination under a set of
conditions
APPLICATIONS
• Barrier leak control
• Ef uent release monitoring
• Radioprotection of workers
• Operational process monitoring
• Post-accident operations
FEATURES

SETTING SIMULATION PARAMETERS
A simulation contains six functional groups of parame-
ters. Parameters saved can be entered manually or read
in a  le. These groups of parameters are as follows:
General: name of the simulation, units used through-
out the simulation, origin of the measurements, etc.
Scenario: description of the evolution of the measure-
ment conditions over time, including:
Simulation durationEvolution over time of the physical quantities which
in uence the measurements
Events which in uence the measurements
Model: description of the detection assembly charac-
teristics including:
Detection ef ciencies of the radioisotopesSensitivity to the different nuclear backgroundsIntrinsic and electronic noise
Algorithm: description of the algorithm parameters
(accessed from the MASS software)
Analysis: description of the statistical analyses to be
performed:
De nition of the con dence rates to be evaluatedDe nition of bias and standard deviation
Reports: description of the automatic reports to be
made during or at the end of the simulation:
Numerical and/or graphical printingData storage
SIMULATION BASED ON REAL MEASUREMENTS
It is possible to perform simulations in which the input
values provided to the algorithm are not simulated
values but are real measurements stored in ASCII  les.
REPETITION OF IDENTICAL SIMULATIONS
The same event can be performed several times with
this SIMS functionality. This is especially advantageous
when evaluating response times. Indeed, if several iden-
tical simulations using different pseudo-random number
sequences are performed, reliable statistical information
can be obtained about the response times.
RUNNING A SEQUENCE OF SIMULATIONS
The SIMS software allows independent simulations to be run sequentially and automatically using a “batch” method.
