Question Modifying alpha-energy in radioactive decay

I'm trying to modify the alpha energy in my simulations with radioactive decay. I assumed that it should be enough to change the Q-value in radiation decay file, here (last column):

# 210RA (   3.7 S   )

#  Excitation   Halflife Mode         Daughter Ex             Intensity           Q
P       0.0000   3.7000e+00
                             Alpha      		 0.0000   	        1.0000e+00
                             Alpha       		0.0000   		9.9970e+01   7160.3833 
                             Alpha     		575.3000   	3.0000e-02    6577.2816 
P    2053.5000   2.2400e-06
                                IT       		0.0000   		1.0000e+00

But playing with this number has absolutely no effect on the energy of alpha particle.

Same problem with Cf238 in example rdecay01.

So, I guess it's not the Q-value that defines the alpha energy in Geant4. Could you tell me how do I modify it then?
