Maximum quantity(grams)per year of uranyl acetate to exempt from radioactive license

[sergio fierman <sergio@bgumail.bgu.ac.il>]

Dear radsafers

I would like to receive suggestions on how to deal with our electronic 

microscope laboratory workers:

1- The electronic microscope is exempt of radioactive control in Israel.

2- The uranyl acetate that is used with the microscope is considered 

   radioactive( 0.17 microcurie per gram).

3- The maximum amount used per year in our laboratory is 12 g.


Is it necessary to ask for a license to use this material?

What is the ALI for uranyl acetate?

Are there any long radiation effects for such annual quantity?

What arguments can I use to convince the lab. workers that there is no 
danger at all whit such quantities?

Thanking you in advance

Sergio
