|  Dear Theo,  First 
of all it is important to follow the waste management strategy of the Member 
State. You have to ask Guidance from your Regulatory Authority. Here we can 
discuss opinion. One example of a waste management strategy for countries 
without nuclear programme (power reactor and fuel cycle), however with large use 
of sources in industry, medicine and research, you can find in the following 
IAEA TECDOC:  Management of small quantities of radioactive waste, TECDOC 
1041, September 1998. Look the figure 1. If such 
strategy is applied in Greece, you should follow the recommendation, where 
appropriate to short half life and to those < 100 d and they should be 
disposed  following storage to allow 
for decay at clearance levels. If, to radionuclides <100d, the clearance 
levels were not reached, you have only two alternatives. Store until Clearance 
is reached or to send a Landfill Disposal.  I suggest you also the 
following TECDOC, directly at the point of your interest: Clearance of 
materials resulting from the use of radionuclides in medicine, industry and 
research, IAEA TECDOC 1000, February 1998. Jose Julio Rozental Israel
