U-239 has a half life of only 23 minutes so your strategic stockpile of U-239 bombs isn't going to be good for very long. The two isotopes are similar in another way too, they both produce so many gamma rays even a suicidal terrorist in a led suit would be dead before he was half finished making the bomb. <br>
