Only the big ones.  If you want 24 kg of Pu 239, it takes a tenth of kg of 
neutrons to make it.

I used to get bronchitis every year, secondary to virus infections.  It is 
well known that zinc cuts the duration of colds even if you start taking it 
after you get the cold.  So I started taking 50 mg of zinc a day 
preemptively many years ago.  Have since rarely had even the first sign of 
a cold and other than one time when I could not get zinc, no bronchitis.
