ionizing radiation sources and the sources involved in such practices from some or all regulatory conditions) (18 pages, in Spanish) 
6. Description of content:   The notified Standard appli es to practices and the sources 
involved in practices, which, due to their ch aracteristics and intensity, may be exempted 
from all or some of the regulatory controls established by the National Commission for Nuclear Safety and Safeguards. 
This Standard does not apply to ionizing ra diation-generating equipment used for medical 
diagnostic purposes, naturally occurring radioactiv e material, or the transport of radioactive 
material. G/TBT/N/MEX/210 
Page 2  
 
   In some practices using sources, the quantity of radioactive material or the level of ionizing 
radiation involved poses no risk to the populatio n or the environment, in which case it is 
unnecessary and impractical to establish regulator y radiological safety controls for such 
sources.  For this reason, the notified St andard establishes conditions for exempting 
practices and sources from some or all of the regulatory controls established by the 
National Commission for Nuclear  Safety and Safeguards.

To establish specifications for exempting practices and sources.
