Initial Operator Training for the 

RS-2000 X-Ray Irradiator

 

  

This training module is intended to provide 
initial

radiation safety training for 

individuals who wish to use

the Rad Source 

RS-2000 X-Ray irradiator at the 
University

of Minnesota. 

 

The following topics will be discussed in this training; 

 

1.

 

  -  What are Ionizing Radiation and X-rays? 

 

-  How are X-rays produced? 
-  Radiation Dose 

 

-  Health Effects & Regulatory Dose Limit 

 

-  General Hazards Associated with the X-Ray Irradiator 
-  Safety Instructions Regarding the RS-2000 Irradiator 
-  Operating Instructions for the RS-2000 Irradiator 

 

2.

 

More complete and detailed information regarding the RS-

2000 can be found in the RS-2000 Owner’s Manual (one 

manual in each of the irradiator rooms) or by going to 
the Rad Source website (

www.radsource.com

).
