DCYTIMES


    defines decay times for radioactive product scoring

    See also DCYSCORE, IRRPROFI, RADDECAY, RESNUCLEi

    Option DCYTIMES defines the times with respect to the end of the irradiation
    at which selected quantities (e.g. residual dose) are scored.

     
WHAT(1)
= cooling time (in s) after the irradiation end, to be associated to a scoring detector (see Note 1 below) >=< 0.0 : a new decay time is added with delay
WHAT(1)
Default
= 0.0
WHAT(2)
= the same as
WHAT(1)
(one more cooling time)
WHAT(3)
= the same as
WHAT(1)
(one more cooling time)
WHAT(4)
= the same as
WHAT(1)
(one more cooling time)
WHAT(5)
= the same as
WHAT(1)
(one more cooling time)
WHAT(6)
= the same as
WHAT(1)
(one more cooling time)
SDUM
= not used
Default
(option DCYTIMES not requested): no decay times are defined
Notes:
1) Each cooling time is assigned an index, following the order in which it has been input. This index can be used in option DCYSCORE to assign that particular cooling time to one or more scoring detectors. 2) Multiple cards can be given, up to the maximum number of decay times allowed MXTRDC (MXTRDC = 1500 as of version 2011.2c.5). 3) All decay times are counted from the end of the last irradiation period defined using the IRRPROFI command. A null decay time corresponds to the end of irradiation. A negative decay time indicates a time during the irradiation. 4) If a time is indicated more than once, only the first occurrence will be considered and the repetitions will be ignored.
Example 1:
*...+....1....+....2....+....3....+....4....+....5....+....6....+....7....+....8 * Six different times for scoring have been defined, each with an index * corresponding to its input order: * scoring time #1 is 0s, i.e. the end of the irradiation EoI * scoring time #2 is 10s after EoI * scoring time #3 is 30s after EoI * scoring time #4 is 3600s (1 hour) after EoI * scoring time #5 is 43200s (12 hours) after EoI * scoring time #6 is 86400s (24 hours) after EoI
Example 2:
*...+....1....+....2....+....3....+....4....+....5....+....6....+....7....+....8 * Six different times for scoring have been defined, each with an index * corresponding to its input order: * scoring time #1 is -86400s (24 hours) before EoI * scoring time #2 is -3600s, (1 hour) before EoI * scoring time #3 is 0s, i.e. at EoI * scoring time #4 is 3600s (1 hour) after EoI * scoring time #5 is 43200s (12 hours) after EoI * scoring time #6 is 86400s (24 hours) after EoI
Example 3:
*...+....1....+....2....+....3....+....4....+....5....+....6....+....7....+....8 * Five different times for scoring have been defined.
WHAT(5)
hasn't been * provided and the default 0.0 is taken. Therefore six scoring times are * available: * scoring time #1 is 10s after EoI * scoring time #2 is 30s after EoI * scoring time #3 is 3600s (1 hour) after EoI * scoring time #4 is 43200s (12 hours) after EoI * scoring time #5 is 86400s (24 hours) after EoI * scoring time #6 is 0s, i.e. at EoI
Example 4:
*...+....1....+....2....+....3....+....4....+....5....+....6....+....7....+....8 * Four different times for scoring have been defined.
WHAT(5)
and
WHAT(6)
* haven't been provided and the default 0.0 is taken. The duplicated times are * ignored. Therefore three scoring times are available: * scoring time #1 is 10s * scoring time #2 is 3600s, i.e. 1 hour * scoring time #3 is 0s, i.e. the end of the irradiation
Example 5:
*...+....1....+....2....+....3....+....4....+....5....+....6....+....7....+....8 * Eight different cards with one time each have been used. The default 0.0 is * taken for all the WHATs that haven't been provided. The duplicated times are * ignored. Therefore five scoring times are available: * scoring time #1 is 10s after EoI * scoring time #2 is 0s, i.e. at EoI * scoring time #3 is 30s after EoI * scoring time #4 is 3600s (1 hour) after EoI * scoring time #5 is 86400s (24 hours) after EoI
