I have my relatives log book, it has a lot of code names regarding his training, where can I find out what these codes mean?

Pleased that we can help a little with this. 

But word of advice - never send the original log book to anyone unless you are sure who they are and always send it in secure post. Many unscrupulous people out there who collect these for one reason or another. We have been contacted on more than one occasion from relatives who have sent off originals never to see them again.

If you wish to donate such items obtain advice first and even so, make copies prior to sending them.
