When I worked there, and I spent 2 field seasons in 1993-94 in the 80-120Ci&#x2F;sq.km zone, we had two proverbs, briefly translated as: &quot;If you want to be a parent, keep you balls contained in lead&quot; and &quot;You can eat apples here, but you should bury stubs at least 140 cm deep&quot;. Only the second one was true. Mesocarp of fruits was clean, but seeds were normally contaminated with Cs 137 (replaces potassium in meristema).
