DCYTIMES


    defines decay times for radioactive product scoring

    See also DCYSCORE, IRRPROFI, RADDECAY, RESNUCLEi

    Option DCYTIMES defines decay times after irradiations at which selected
    quantities (for instance 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
= scoring at end of irradiation is associated with index 1
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 desired number of decay times. All decay times are counted from the end of the last irradiation period as defined by the IRRPROFI command. A null decay time activates scoring exactly at the end of irradiation. A negative decay time is admitted: scoring is performed at the chosen time "during irradiation"
Example:
*...+....1....+....2....+....3....+....4....+....5....+....6....+....7....+....8
DCYTIMES 10. 30. 3600. 43200. 86400. 172800. DCYTIMES 2592000. 31557600.
* Eight different cooling times have been defined, each with an index
* corresponding to its input order: cooling time no. 1 is 10 s, no. 2 is 30 s,
* and those from no. 3 to 8 are respectively 1 h, 1/2 d, 1 d, 2 d, 30 d, 1 y
