EPA: Types of radiation

["Bjorn Cedervall" <bcradsafers@hotmail.com>]

Browsing through the "educational" EPA page about radiation
http://www.epa.gov/radiation/students/
one finds "Radioactive alpha particles" and "Radioactive beta particles"... 
May be it is nuclear particle physics they are describing - probably not. 
The words and concepts are important - especially when texts are aimed for a 
broader "non-scientific" community. Perhaps someone with the right contacts 
could give EPA a hint - or am I all wrong?
