3. DESCRIPTION OF PROGRAM OR FUNCTION

DecayHeat.MT calculates the decay heat from radioactive isotopes as time passes. Time intervals are 5; 0.1 sec for 0 to 1 sec, 1sec for 1 to 1000 sec, 10 sec for 1000 to 10000 sec, 100 sec for 10000 to sec and 1000 for 100000 to 1000000 sec. As the output, this program shows that multiplication of time and decay heat of alpha, beta, gamma, neutrino and total. In other words, α decay heat t*a(t), β beta decay heat t*b(t), γ decay heat t*g(t), energy carried by neutrino t*n(t) and total decay heat t*total are reported for each time bins. Note that energy emitted by neutrino is not included in total, i.e. total = a(t) + b(t) + g(t).

4. METHODS

The Monte-Carlo method is used.

6. TYPICAL RUNNING TIME

The running time of the calculation depends on the number of input isotopes and the number of events. A calculation of 1,000,000 events with 1000 isotopes takes about 90 seconds on an Intel i7 dual core process (1.90 GHz).

7. UNUSUAL FEATURES OF THE PROGRAM

The latest update ENSDF can be used for the calculation of cumulative fission yields and radiation spectra.
