Sectors of activity

• Available packaging

Radioactive standard solutions are usually supplied in sealed glass ampoules.

High-activity solutions are supplied in capped vials for ease of handling.
Packaging is designed to prevent evaporation during transport and storage.
Large-volume solutions for environmental measurements are supplied in plastic vials.

• Volumes

The standardized volumes (1, 5 and 20 cm³) shown in the tables are determined with an uncertainty of 0.2% (k = 2).
The volumes 50 and 500 cm³ are given as indicative values, but the masses of solution are nevertheless certified to within 0.2% (k = 2).

• Density

Density is generally very close to 1 g.cm^-3, and is stated on the calibration certificate.

• Chemical composition

Chemical composition is shown in the tables as an indicative value only, and is subject to change without notice. The composition shown on the calibration certificate must be complied with in case of dilution.

• Calibration variable

Standard solutions are characterized in terms of specific activity, expressed in kBq.g^-1, with the exception of multigamma ray standard solutions, which are characterized in terms of photon flux per unit mass within 4 pi sr, expressed in s^-1.g^-1.
The stated activity applies to the main radionuclide, and excludes decay products and identified impurities.
The available nominal specific activities are defined for each radionuclide in the solution tables.
Other radionuclides and different activity levels can be supplied on request.
