1) Because the author whose work I want to verify used this kind of
detector. (I am not yet completely sure that I will do this.)
2) May I suggest that acronyms be always explained in our messages.
Why to assume that everybody knows what MPT stands for? Why
should a reader be distracted from the essence of a message by
trying to guess what an acronym or an abbreviation is for.

Why don't you use a phosphor and a MPT, a lot faster and one can

CR-39: polyallyl diglycol carbonate.
This was apparently a material adopted by U Bristol (UK) for radon
testing etc.
I see that a UK distributor is offering a kit of 30 one square inch
squares
for schools, where the development is included in the price of around
$50.
That offer is UK only.
If all else fails, I could ask a UK correspondent to order some for
you, and
pass on the developing.
But there must be a US supplier - can't find it quickly on the net
however.

Can somebody send me pieces of CR-39 plastic, often used to
detect alpha particles, for example from radon. Tracks of alpha
particles stopped in sheets of that material become visible (and
countable) under microscope, after being etched in NaOH. I will
be happy to reimburse you. Please contact me first at
