Nuclear Spectroscopy

Cardwell, and especially Robert Bradford. I want to
thank Sherwood Ebey for his critical review of Experiment
#9; Clay Ross for his help with Mathematica; Ed
Kirven for providing some critical help with the chemistry
and the chemical supplies; and Frank Hart and
Polly Peterson for their critical and timely review of
this book.
There are several people who have helped me develop
my own teaching of nuclear science. This book would
not have been possible without their unfailing support
and kindness - Roger Stevens, first at the Nucleus and
now at Spectrum Techniques; Paul Frame at O.R.I.S.E.;
and Jerry Duggan and Floyd McDaniel at the University
of North Texas. Thank you.
Finally, I want to thank my wife, Peggy, and my two
daughters, Carrie and Abby, for their support, help,
and understanding during this writing and testing.

Summary of Radiation-Related Units
Activity a measure of the number Curie (Ci) 1 Ci = 3.7 x 10 10 Bq
of nuclear disintegrations Becquerel (Bq)* 1 Bq = 1 disintegration/sec
per second
Exposure amount of ionizing radiation Roentgen (R)
that produces 2.58 Coulombs rate as R/hr
per cm 3 of STP air
Absorbed total energy absorbed from rad 100 rad = 1.0 Gy
Dose ionizing radiation per mass Gray (Gy)* 1 Gy = 1.0 J/kg
of the absorber
Dose measure of the biological rem 100 rem = 1.0 Sv
Equivalent health risks; absorbed dose Sievert (Sv)*
times the Q factor
*Denotes SI unit.
