Is there someone there who could answer a few questions about my Drosophila
science fair experiment? My plan has been approved by my teacher and by the
local science fair board. I could fax a copy of it to anyone who would take
a few minutes to give me some comments.
I am exposing drosophila to 3 types of radiation, looking for mutations: UV
rays, x-rays, and microwaves.
I need to know how much of each radiation to expose them to so I'm not just
wasting time and the experiment doesn't really prove anything. For example,
in my reasearch, I read that it takes "a lot" of x-ray radiation to cause
the genetic mutations, but they didn't define "a lot."
My orthodontist said he will do the x-rays for me, but I need to know how
many times to ask him to "zap" the flies.
Also, I tested the microwave oven using common house flies, but they died
with as little as 10% power for only 8 seconds. Do you know of another
microwave source I could use? If I just put them right outside the
microwave door would they get enough? For how long?
I ordered a UV lamp and plan to expose the flies for 24 hours a day for
about a week. I read that UV is very low level. Do you think this will be
enough? Too much?
THANK YOU!! THANK YOU!! THANK YOU!!
