No Dave, he'll need to turn his mower into one of these
http://tractors.wikia.com/wiki/County_Sea_Horse  Since it took 7 hours
to cross the English channel, which my simple brain calculates to be a
speed of about 4 knots, it will take him about 10 days with a following
wind to reach Southampton from New York and a further day or two
(depending on traffic) to reach Birmingham. If he gets here Doug's chair
which I won earlier in the year could do with re-upholstering, it's
looking a bit tatty

Regards
Ian

Hi! Somehow, I think that freezing the northern portion of the Atlantic
ocean solid so that Clumpy can amble over to Ian's facility is going to
make some folks upset. Perhaps we need to give Clumpy a survival suit, a
case of Twinkees, a couple gallons of coffee and a jet ski as an
alternative mode of transportation.

RE: [TN] NTC Friday Element Quiz On Thursday - the Answer






Unless you live in Minnesota, you do not quickly know the answer to "how
to drive a John Deere across the ocean". It's simple, you wait until
January and take a somewhat northerly route. With the three-point snow
blower attachment, there is nowhere you can't go with a Deere.

Subject: [TN] NTC Friday Element Quiz On Thursday - the Answer

The Question: 

I am an element that was first produced in the 1940's. This element
decays 


by both alpha and gamma which poses serious safety issues when handling
large quantities. However, this element is considered an inexpensive
radiation source for portable gamma radiography of welds and as a
thickness gauge in the manufacture of glass. The alpha radiation
characteristics provide an ionization source for smoke detectors. A
typical household smoke detector contains 200 ug of this element. What
element am I?


The Answer:

The element is Americium (Am). The US Government nuclear fuel
reprocessors 

sell AmO2 to licensed commercial users at $1500 per gram. In a smoke
detector, the AmO2 alpha particles ionize the air in the detector,
allowing a continuous current flow through the detection chamber. Smoke
particles entering the space between the chamber's electrodes absorb
much of the alpha radiation reducing the ionization of the air thus
changing the current flow causing the alarm to trigger. The radiation
dose to users 

of AmO2 smoke detectors is near zero because the detector case absorbs
the 

alpha rays and the gamma ray intensity is quite low.

The winner of the quiz was Bev Christian of RIM. However, the Friday
Element Rules Committee does not allow Clumpy to visit the same company
more than once (sorry Bev, you'll need to file a 2345678B form with the
committee for an appeal) so Clumpy is now headed to visit Ian Fox,
Goodrich, for his next weekly assignment. How the heck he is driving the
mower over the Atlantic ocean is beyond me. 

Clumpy's task accomplishments:

Week 1 - accomplished nothing
Week 2 - conducted REACH material testing Week 3 - Solderability testing
