4 out of 5 stars review

Good overall

1) A few of the seed group results showed growth in groups that should not grow or vice versa: evidence that the seed packets may be mislabeled or that the seed contents were switched during the packaging process. These results can bring up an opportunity to question students about the cause of such results. 2) In the past, I have advocated adding a few seed groups between the middle dose (500 krads) and the extreme dose of 4000 krads.
