[ RadSafe ] RE: Little Leagues and Radioactive Terrorism

According to the 'old' Radiological Health Handbook it's production is from 
its daughter (progony) Np-238 from  Np-237 (n,Gamma), NP-237 producition can 
be from U-238(n, 2n )U-237(beta minus.  Np-238 can be from U-238 (d,2n) 
U-238 (p,n).

I think the production is:  U-235 activates to U-237-decays to Np-237 
activates to Np-238 decays to Pu-238

John,

The U-238(n, 2n)U-237 reaction has a threshold of 6MeV -- no yield in a
reactor.

I believe the process requires U235, not U238.

Mike

I have done bioassay for Pu-238. I think it was "made" in reactors by the
U-238(n, 2n)U-237 ->Np-237(n,gamma)Pu-238 process.
