Subject: Does electromagnetic waves have any harmful effects of plant growth?

I'm doing an experiment about the effect of microwaves on seeds. Seeds 
using: radish, lima bean, peas, and blue lake bush bean. Step 1: Using an 
egg carton filled with potting soil and marked "0" by the first two 
pockets, "5" by the second set of pockets, "10" by the third, "15", "20", 
and "25" by the next ones. These numbers stand for the number of seconds 
the seeds will spend in the microwave (they are "nuked" dried). Using two 
seeds for each kind and "nuking". the "0" means that these seeds spent no 
time in the oven. (Microwaved each at high power and no water in the 
oven). After "nuked", they are planted to their proper holes and watered. 
All are given the same amount of sunlight each day. Conclusion: the radish 
seeds that were nuked for 25 seconds germinated first in the fifth day. 
Radish seeds "nuked" for 10 seconds germinated 10th day. Others have not 
germinated. Blue lake bush beans germinated at 5, 10, and 25 seconds 
first; the peas germinated at 5, 10, 15 and 25 seconds; lima bean 
germinated at 10 seconds. I hypothesized that the microwave will harm the 
seeds but I have been proven wrong. Ok, then why didn't it? I was told 
that the electromagnetic waves can be dangerous to people. Why?
