Source Stabilization
Method to continuously adjust for the drift of a detection system by measuring the radiation
of a known reference source.
*.spc
A ile format used by former measuring instruments to store spectrum data. Was replaced
by the more versatile and standardized ÚANSI N42.42 format.
Specic Activity
The ÚActivity in ÚBecquerel per amount of substance. The amount is usually given as mass
for solid matter (Bq/kg, “speciic activity” sensu stricto) or as volume for liquids (Bq/l, activ-
ity concentration).
Also known as: Activity Concentration
Spectrum
The continuous arrangement of the components of ÚRadiation in a progressive series ac-
cording to a characteristic quantity such as wavelength, frequency, energy, charge, mass etc.
Using this arrangement as one axis, another quantity, e.g. intensity, can be plotted along a
perpendicular axis
Digital spectra are discrete, that is they collect the plotted quantity into separate channels
representing a (small) range of the characteristic quantity.
Standard Operating Procedure (SOP)
A set of instructions for a procedure to be executed always in exactly the same manner.
Also known as: Standing Operating Procedure

Technologically Enhanced Naturally Occurring Radioactive Material (TENORM)
ÚNaturally Occurring Radioactive Material as used in, for example, oil and gas exploration,
development and production operations.

Tethering
Using a mobile device such as a mobile phone to supply Internet access for another device
which is otherwise unconnected, using the mobile device as a modem. This can be done
through, for example, ÚBluetooth wireless technology or cables (such as ÚUSB).
