******In intersting news: I was irradiated today! *******
We got to bombard manganese solutions with neutrons, and then measure the beta particles released with a scintillation counter.
We started diluting, and 15-30 min, the fire alarm rang, first in spurts, as we wondered "can we ignore this? I just started to____ and I don't want to stay here all night my chem 320 is due tommorow!" When the signal became steady, we were herded to the door. A rare chance to chat with one's class mates, in awkward atrophied loss of social skills and suffering fatigue.
Anyways dilution... and then we poured our samples into these little plastic vials that had velcro on the top. Then we stuck plexiglass rods on top by the velco, and *all at the same time* lowered the vials into numbered holes in the top of a metal canister that contained the radioactive neutrino source. Ooohhhh.
We had to wear gloves taking them out.
Then we scintillated them... and did a "wipe test" to ensure we hadn't been unduly irradiated.
Now back to checking the cluster... sigh, you'd think a class of 60-100 could share a 31 node cluster. :P
