HEALTH PHYSICS PROCEDURE HPP 6-2 LAB RADIOACTIVE GASTE COLLECTION 07 Jul 87 1.
General a.
Purpose and Scope: This HPP describes the procedures to be followed in collecting laboratory radioactive wastes and transporting them to SAF areas used for their storage and/or treatment.
b.
Responsibility:
(1) SAF personnel are responsible for pickup, storage and preparation of radioactive waste, and laundering and surveying of radioactive laundry.
(2) Radioactive source users are responsible for documenting radioactive inventories for waste containers, and assuring that documentation is correct within the limits prescribed in this procedure.
2.
References a.
Regulatory:
(1) 10 CFR 20, " Standards for Protection Against Radiation" (2) RSI 610, " Laboratory Radioactive Waste Disposal" (3) 49 CFR, " General Requirements for Shipments and Packaging" b.

Laboratory Waste Pickup Frequency Radioactive vaste will be picked up by SAF, whenever a pickup is requested a.
by any AFRRI laboratory personnel.
Pickups are normally made within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of the request.

Lab Wasta Categories a.
Summary of Categories (refer to RSI 610):
(1) Low-level liquid, limits in 10 CFR 20, appendix C and 10 CFR 20.B.I.2.,
and containing a one-liter or more volume 6-2-1 8708170150 070007 PDR ADOCK 05000170 0

(2) High-level liquid,.above low-level limits (3) -Solid waste; e.g., glassware, papers, dry vials, including concentrated waste, but not reading more than 2.5 mR/h at contact (4) Solid waste producing radiation area; i.e., >2.5 mR/h at contact (5) Scintillation vials (6) Partially expended radioactive sources (7) Animal carcasses, injected or activated b.
Treatment and disposal of radioactive waste shall be according to the specific requirements of that type of waste.
5.
Storage and Disposal a.
Solid waste: All waste categorized in paragraph 4.a., numbers (4), (5) and (7) shall be stored in radioactive barrels, or in boxes in the freezer.
b.
Animal Materials: Carcasses and organs of animals which have been injected with radioactivity, or made radioactive by exposure to a reactor or similar source, shall be stored in a cold storage araa, in barrels marked "ANIM".
Such barrels, if not stored in a posted, locked room, shall be labeled as "RADI0 ACTIVE MATERIAL".
c.
Vials: Vials containing up to 20 ml of radioactive liquid may be stored in waste barrels marked " Liquid Scintillation VIAL /LSV", in the radioactive storage area.
No treatment of these vials is required, at AFRR1.
The se vials should be kept closed during storage.
6.
Lab Waste Container Documentation a.
Documentation Limits: Source users shall document all radioactive materials placed in waste containers.
b.
Rad Waste Tag: Documentation shall be made on the " Solid / Liquid Radioactive Waste" tags (enclosure 2) which shall be provided by SAF with each waste container. Additional tags may be obtained from SAFH.
c.
SAF personnel shall complete the tag and review documentation at the time of picLup. All disposal entries shall include:
(1) Disposal date (2) Specific radionuclides (3) Amount of each, in millicuries (4) Physical and chemical designation of the material 6-2-2 i
f M _ ".
'(5) Enumeration of all non-radiological hazards
-(6) Person disposing, signature-initials,_and
.(7) Person' picking up, initials.
d.
If. documentation is incomplete or questionable, collection shall not be made until the senior member of SAFH has been contacted.
Non-radiological hazards labeling shall be deemed fully as important as radiological labeling. Liquid lab waste should be sampled right after pickup.
l 7.
- Waste Barrel Documentation a.
General Contents: Each amount-of radioactive material deposited in any waste barrel shall have with it information as to its general contents.
This should include the types and quantities of radioactive material.
b.
All waste barrels shall have Radioactive Waste Cards (AFRRI Form 117) reflecting the current radioactive material contents firmly attached and I
visible.
l c.
All waste barrels will be clearly labelled with a " CAUTION RADIOACTIVE MATERIALS" sign including the radiation symbol.
d.
If the types and quantities of radioactive material are not directly obtainable, they shall be estimated as follows:
(1) Source users shall be interviewed to determine what significant-l (microcurie) amounts of activity have been placed in laboratory containers.
(2) RAL records shall be reviewed to determine.5e content of vials removed from AFRRI Room 1426.
Analogous records shall be reviewed in-any other

laboratory using counting vials.
~
(3) Random sampling of solid and LSV waste shall be used if necessary.
(4) For labeling barrel see 49-173.421, 173.444, and 10 CFR 20.203(F).
c.
If a range of activity estimates is obtained, the upper extreme of the range shall be recorded for use on waste disposal documents.
