It is advisable to monitor these materials for contamination, and contaminated materials should be held for an appropriate period of decay-in-storage before disposal [ 52, 59].
61 It is advisable to monitor these materials for contamination, and contaminated materials should be held for an appropriate period of decay in storage before disposal.
"If the crews see that there is contamination, other materials, in that bag or can, they're going to leave it there.
(Other commercial isotopes, such as polonium, which was employed in London last autumn to murder the former Russian spy Alexander Litvinenko, can kill individuals or small groups but cannot cause damaging long-term ground contamination; these materials are not classified as a security risk).
To eliminate organic contamination, all materials in contact with the reacting fluid were baked in a muffle furnace at 450 °C for 5 h.
Laboratory testing using blank solutions shows minimal sources of contamination from materials used in the construction and sampling procedure (i.e. titanium, MilliQ water and aqua regia).
The work was done in separate centers to provide verification of data, and stringent precautions were taken against contamination (Supporting Materials and Methods S1).
We used dBPA in experiment 1 because it can be clearly distinguished by isotope-dilution LC-MS, thus eliminating concern about potential BPA contamination from materials used in the preparation, handling, or shipment of samples.
The collision can result in a release of some material from the tip (be it contamination or material of the tip itself) or in a capture of some material from the surface.
"There's no cross-contamination of materials," Grey told me.
