I_{d   (HINT: HVL)}

What is Desired Intensity?

400

 I_{o     (HINT:  HVL)}

What is original Intensity?

500

100 ci of IR 192 emits how many R/hr in air, at one foot?

ALARA

What is As Low As Reasonably Achievable (or Attainable)?

200

HVL

What is Half Value Layer?

300

RSO

What is a Radiation Safety Officer?

400

SI

What is the International System of units of measurement?

 (Includes most of the base units formerly called metric.)

500

AHBA

What is the American Honky Tonk Bar Association?

CHALLENGE Q's

100

These three things encompass the essence radiation safety.

What are Time, Distance & Shielding?

200

A nuclear reaction in which atomic nuclei of a lower atomic number fuse to form a heavier nucleus with the release of energy.  The sun is an example of this process.

What is Nuclear Fusion?

300

The process by which the nucleus of a stable atom splits upon impact of another particle and splits into 2 smaller parts.  The resulting atoms are not the same element as the parent atom and are considered unstable and radioactive.  This is the process by which Industrial isotopes (Cobalt 60, Iridium 192, Cesium 137) are created.

What is Nuclear Fission?

400

This NDT JOKER has a lot in common with a goofball named "Gilligan".

Who is Zak MILLIGAN?

500

This local government agency is credited with developing the process to create Zirconium for the US navy Nuclear Propulsion Program in the 1940's.

Who is the Albany Bureau of Mines?
