Re: rad_waste_clearence_levels



 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.

Hi, everyone,

I am a new subscriber to this interesting discussion list.

 

My question is:

Do you think that we have to apply the CLEARENCE LEVELS as they are defined within European legislation http://europa.eu.int/comm/environment/radprot/122/rp-122-en.pdf (especially in solid form) to the radioactive waste generated from a Nuclear Medicine dept.?. Think about I-125 tubes from a RIA dept., or the solid I-131 radioactive waste generated during the hospitalization of thyroid ablation therapy patient.
