Special rules of classification

Classification of both important (invention) information and additional information is obligatory.

Shielding characterised by the composition of the materials
Definition statement

This place covers:

Shielding characterised by the specific material or composition chosen for obtaining the protection against ionising radiation.

References
Informative references

Attention is drawn to the following places, which may be of interest for search:

Lime, magnesia; slag; cements; compositions thereof, e.g. mortars, concrete or like building materials; artificial stone; ceramics; refractories; treatment of natural stone

Shielding characterised by its physical form, e.g. granules, or shape of the material
Definition statement

This place covers:

Both the physical form of the shielding and the physical form of the shielding material or composition used to make the shielding. The subgroups only cover the physical form of the shielding itself. G21F 1/00 covers the material compositions, i.e. the choice of materials, G21F 3/00 the shape that such composition takes.
