Definition statement
This subclass/group covers:

Shielding providing protection against ionising radiation, i.e. against x-radiation, gamma radiation, corpuscolar radiation or particle bombardment; devices and methods to treat radioactively contaminated materials.

References relevant to classification in this subclass
This subclass/group does not cover:
Radiation protection by pharmaceutical means
A61K7/40
Use of cosmetics or similar toilet preparations already classified as such in A61K 8/00 when brought into direct contact with the skin (i.e. topical preparations) for affording protection against X-rays or other harmful rays
Radiation protection in cosmonautic vehicles
Shielding structurally associated with a reactor
Vessels, containers or shields associated with X-ray tubes
X-ray producing apparatus involving X-ray tubes; constructional details thereof; control thereof; circuits thereof
Apparatus or processes for producing X-rays, not involving X-ray tubes, e.g. involving generation of a plasma
Screening of electronic apparatus or components against electromagnetic fields

Examples of places where the subject matter of this subclass is covered when specially adapted, used for a particular purpose, or incorporated in a larger system:

Special rules of classification within this subclass

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

Shielding characterised by the composition of the materials
Definition statement
This subclass/group covers:

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

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

Informative references
Attention is drawn to the following places, which may be of interest for search:
Protective clothing or garments in general
Radiation protection in radiation diagnosis apparatus, e.g. combined with radiation therapy equipment
Transportable or portable shielded containers
Definition statement
This subclass/group covers:

Details of transportable containers for materials or structures emitting ionising radiation.

Informative references
Attention is drawn to the following places, which may be of interest for search:
Radiation protection in radiation diagnosis apparatus, e.g. combined with radiation therapy equipment
Vehicles adapted for load transportation, to carry or to comprise special loads or objects
Containers for contents presenting particular transport or storage problems
Shock absorbers per se
Storage racks within reactor storage pool
Shielded cells or rooms (chambers provided with manipulating devices in general B25J)
Informative references
Attention is drawn to the following places, which may be of interest for search:
Chambers provided with manipulating devices in general
Glove-boxes in general
Control or regulating systems in general
Treating radioactively contaminated material; Decontamination arrangements therefor
Definition statement
This subclass/group covers:

Treatment of radioactively contaminated material and all decontamination arrangements therefor as well as the decontamination of contaminated objects, apparatus and clothes and the decontamination of surfaces.

References relevant to classification in this group
This subclass/group does not cover:
Reprocessing of nuclear fuel
Informative references
Attention is drawn to the following places, which may be of interest for search:
Separating different isotopes of the same chemical element
Reclamation of contaminated soil
Ingredients generally applicable to manufacture of glasses, glazes, or vitreous enamels
Ingredients generally applicable to manufacture of glasses, glazes, or vitreous enamels
