Marlin:
The modern smoke detector, responsible for saving so many lives in house fires, can be traced back to 1899 when, at McGill University in Canada, ___________ blew tobacco smoke into his ionization chamber and observed the change in ionization.


Fill in the blank and for a bonus question...what would his annual exposure be from smoking unfiltered cigarettes?

Marlin:
Match the following "Rays" to discovery method and discoverer.

Beta and Alpha Rays       ___  ___
Gamma Rays                  ___  ___
N Rays                          ___  ___
X Rays                          ___  ___

1...Rene Blonlot
2...Wilhelm Rontgen
3...Paul Villard
4...Ernest Rutherford

A...Discovered when a calcium sulfide thread glowed slightly in the dark while bending radiation 60 degrees through a prism.
B...While using a Rumkoff induction coil to produce a stream of charged particles noticed a shimmering light from fluorescent material laid on a table a few feet away from the apparatus.
C...While measuring the refraction of alpha and beta rays from uranium noticed that in almost every experiment the photographic plate revealed a non-refracted beam.
D...While experimenting with radiation exposure to a photographic plate it was noted that a thin shield produced a diffusion of the photographic image.

Marlin:
   Any trivia questions I post will be followed up with an answer in about a week (plus or minus a week or two). The question above on "rays" I beleive can be answered 75% with fundamental RadCon theory without any research for most Rad Techs.

   I request that anyone posting a Trivia or History question also provide answers within a reasonable time frame or simply post a Trivia or History fact if you do not intend to follow up.

Beta and Alpha Rays..Ernest Rutherford......While experimenting with radiation exposure to a photographic plate it was noted that a thin shield produced a diffusion of the photographic image.


Gamma Rays............Paul Villard.................While measuring the refraction of alpha and beta rays from uranium noticed that in almost every experiment the photographic plate revealed a non-refracted beam.
           

N Rays ...................Rene Blonlot............ Discovered when a calcium sulfide thread glowed slightly in the dark while bending radiation 60 degrees through a prism.
 

X Rays ...................Wilhelm Rontgen........While using a Rumkoff induction coil to produce a stream of charged particles noticed a shimmering light from fluorescent material laid on a table a few feet away from the apparatus.


   The N Ray was the "cold fusion" of its day. When an English scientist was unable to reproduce the experiment it was declared that the English eye was not able to tell the difference in the glow of the thread. It was not until Blonlot's death that the theory declined from favor.
