Development Of A Chemical Dosimeter Readout System, Everett Oscar Richey May 1962

Development Of A Chemical Dosimeter Readout System, Everett Oscar Richey

Theses

One of the various methods for measuring doses of ionizing radiation is the halogenated hydrocarbon dosimeter, also called the "chlorinated hydrocarbon," or the "water equivalent" dosimeter. These dosimeters have a range from ten to greater than 10^6 roentgens, and the response is essentially independent of energy, dose-rate, and temperature. This dosimeter consists, basically, of triply distilled water saturated with a halogenated hydrocarbon and an acidimetric indicator dye. Chemical chain reactions induces by radiation liberate acid and the amount of acid formed is directly proportional to the dose.

Calibration Of An X-Ray Unit As To Effective Wave-Lengths By Comparing Absorption Coefficients, Jerome James Woyci May 1950

Calibration Of An X-Ray Unit As To Effective Wave-Lengths By Comparing Absorption Coefficients, Jerome James Woyci

Bachelors’ Theses

The purpose of this paper is to determine by the mass absorption coefficients of various substances, namely, aluminum, copper and iron, the effective wave-length of an X-ray beam which passes through particular thicknesses of the above materials. Since an X-ray tube does not emit a monochromatic wavelength but emits heterogeneous wave-lengths, we had to use a comparative method in order to obtain the desired results. It happens that the mass coefficient of absorption of carbon does not vary appreciably with an increase or decrease in wavelength, hence, we can use carbon as our standard or material to which we can …

The Tesla Coil, Willard H. Schultz May 1938

The Tesla Coil, Willard H. Schultz

Bachelors’ Theses

The following paper is an attempt to gather together and present in some order a few of the facts concerning the design, theory, and operation of the Tesla Coil. The writer's interest was first directed to the production of high frequency, high potential current by an article appearing on page 594 of the October, 1933 issue of the Popular Mechanics Magazine. Here the construction of a small coil was described. The writer built such a coil and was greatly disappointed with the results obtained from it. As is so frequently the case, this failure only intensified the desire to construct …
