Single nuclide solutions

A wide range of single radionuclides in solution is available with activity concentrations ranging from 4kBq/g to 4MBq/g.
The solutions are supplied in flame-sealed glass ampoules to ensure that none of the solution evaporates during transport or storage.

Solutions designed for calibrating radionuclide calibrators in nuclear medicine departments are supplied in vials, identical to the vials used for radiopharmaceuticals. There is a small risk of evaporation from vials, so the certificate of calibration states the total activity of the radionuclide rather than the radioactive concentration. These solutions are not suitable for sub-division.

Measurement
Two methods are used to calibrate standardized solutions. Both are traceable to national standards.

1) Direct calibration
High accuracy standardized solutions are assayed by coincidence counting techniques. The techniques are similar to those used at national standards laboratories. Directly calibrated solutions are identified by the letter ‘Z’ as the third letter of the product code.

2) Indirect calibration
These solutions are assayed on a highly stable transfer instrument, which has been calibrated continuously for more than 30 years using standards from each batch of directly calibrated solutions. Indirectly calibrated solutions are identified by the letter ‘Y’ as the third letter of the product code. Directly calibrated solutions offer the very high accuracy needed for some applications.

Chemical composition
Most of the solutions also contain non-radioactive carrier element to minimise adsorption of the radioactive material onto the surface of the ampoule. Normally the carrier concentration is 100µg/ml of the inactive element.
