Mailing Samples on Dry Ice
NOTE: Pickup and delivery in the Madison area is free. Call (258-1565) to arrange a time.
Aliquot samples into 1 ml Eppendorf tubes or other small tubes. Label each tube with an identifying number and your initials. Freeze the tubes.
If the samples are radioactive, you must use an inner carton. Partly fill the inner carton with dry ice, add samples, and fill up with dry ice. Mark the inner carton with radioactive tape and the NOTICE OF LIMITED QUANTITY OF RADIOACTIVITY. See below for the wording of the notice and for postal regulations for the radioisotopes. Please send as little radioactivity as possible. Embed the inner carton in dry ice (about 6 lb will last more than 2 days) in the styrofoam mailer.
Put the completed sample ID form (PDF) in the box. If appropriate, make sure you have indicated how samples are to be diluted. Since additional information about the samples often helps in optimization of loads to give better gels, we encourage as much detail as possible. All information concerning samples is held strictly confidential.
Close the styrofoam mailer, stick on the address label and seal with mailing tape. Mail using the overnight service of Federal Express. Check "dry ice" and apply the "dry ice" sticker with number of pounds to outside of package.
MAILING COMMON BIOLOGICAL RADIOISOTOPES
The maximum permissible limits for mailing radioactive liquids via the US Postal Service, without marking the outer package, are as follows:
3H, 10 millicuries; 14C, 600 microcuries 35S, 600 microcuries; 32P, 300 microcuries.
It is essential that radioisotopes be packaged according to the following directions:
- The materials should be contained in strong, tight packages that will not leak any of the radioactive materials during normal postal handling. Liquid radioactive materials must additionally be packaged within a leak and corrosion resistant secondary inner container, surrounded by sufficiently suitably positioned absorbent material to absorb at least twice the volume of the liquid contents in the event of leakage from the secondary inner container.
- The radiation level at any point on the external surface of the package should not exceed 0.5 millirem per hour. To be certain of this, it is necessary to package 32P in lead or plexiglass containers.
- The nonfixed (removable) radioactive surface contamination on the external surface of the package must not exceed the limits 22 dpm/cm2.
- The outside of the inner packaging must bear the marking, "Radioactive". Always have inner packaging.
- No single package dimension should be less than 2.5 cm (1 inch) and the length and girth no less than 30 cm (12 inches).
- A specially worded NOTICE OF LIMITED QUANTITY OF RADIOACTIVITY which can be in or on, or accompany an excepted package of radioactive material should read as follows: "This package conforms to conditions and limitations specified by 49 CFR 173.421 for excepted radioactive material of limited quantity, N.O.S.,UN2910."
Radioactive materials whose activity per package do not exceed the limits specified above and which are properly packed are excepted from specification packaging, marking and labeling requirements.
