Abstract

A light-weight radiation protection panel comprising radiation protection layer and a flexible material. The radiation protection layer comprises a plurality of a shielding material distributed in repeated and adjacent units of geometrical shapes, the light-weight radiation protection panel being able to be embodied in a wearable garment providing flexibility.

Claims (40)

1. A radiation protection panel to protect a living body against space radiation, the radiation protection panel comprising:

a radiation attenuation layer comprising a plurality of shielding elements; and

each of said shielding elements comprising an individual radiation attenuating characteristics;

wherein the individual radiation attenuating characteristic is at least one of a thickness or a density of the shielding element that is substantially inversely related to radiation attenuation levels of tissue present between each of said plurality of shielding elements and the underlying organ of the living body; and

each said shielding element being a geometric shape; and

a flexible material connecting the plurality of shielding elements;

wherein the panel comprises flexibility greater than an individual shielding element,

wherein the plurality of the shielding elements includes a plurality of longitudinal members that are attached to the flexible material, the plurality of longitudinal members result in varying radiation attenuating characteristics across a surface of the radiation protection layer, and each longitudinal member extends further in a direction perpendicular to a plane of the flexible material than it does in a direction parallel to the plane of the flexible material.

2. The radiation protection panel of claim 1 , comprising a wearable garment.

3. The radiation protection panel of claim 1 , the shielding element wherein the geometric shape comprises any three-dimensional form arising from the three-dimensional extrusion of a two-dimensional repeating, adjacent, tessellated pattern such as squares, rectangles, hexagons, triangles, pentagons or any combination of regular or irregular shapes using one or multiple geometrical shapes in a single pattern.

4. The radiation protection panel of claim 1 , the shielding element comprises a friction minimizing material.

5. The radiation protection panel of claim 1 , wherein

the shielding element comprises an outer solid material shell defining an internal cavity;

one of the radiation attenuating characteristics of the shielding element is determined by the composition of the outer solid material shell of the shielding element; and

another of the radiation attenuating characteristics of the shielding element is determined by the composition of the internal cavity of the shielding element.

6. The radiation protection panel of claim 1 , comprising:

a vertical axis;

wherein the shielding element has a thickness defined along the vertical axis;

wherein one of the radiation attenuating characteristics of the shielding element is the thickness of the shielding element; and

wherein the thickness of the shielding element is varied to vary the radiation attenuation of the shielding element.

7. The radiation protection panel of claim 6 , wherein each subset of the plurality of the shielding element having the same thickness is marked enabling the identification of the shielding element having the same thickness.

8. The radiation protection panel of claim 6 , wherein the thickness of the shielding element is oriented perpendicular to a tissue.

9. The radiation protection panel of claim 8 , comprises

at least two light-weight radiation protection panels; and

wherein the at least two light-weight radiation protection panels partially overlap;

wherein the thickness of the at least two are varied to maintain the relationship between radiation attenuation levels of the shielding element and the radiation attenuation tolerance of the tissue protected by the plurality of shielding element.

10. The radiation protection panel of claim 9 , comprising:

the at least two light-weight radiation protection panels comprise a wearable garment.

11. The radiation protection panel of claim 1 , wherein the plurality of longitudinal members have uniform heights, resulting in a uniform thickness of the radiation protection layer.

12. The radiation protection panel of claim 1 , wherein the plurality of longitudinal members have non-uniform heights, resulting in a varying thickness of the radiation protection layer.

13. The radiation protection panel of claim 1 , wherein the longitudinal members are slidable against each other.

14. The radiation protection panel of claim 1 , wherein the longitudinal members are attached to the flexible material on both sides using heat welding.

15. The radiation protection panel of claim 1 , wherein the plurality of longitudinal members includes a first layer of longitudinal members, and a second layer of longitudinal members staggered on top of the first layer of longitudinal members.

16. The radiation protection panel of claim 15 , wherein the first layer of longitudinal members has a uniform thickness.

17. The radiation protection panel of claim 15 , wherein the second layer of longitudinal members has a non-uniform thickness, and includes longitudinal members of non-uniform heights that correspond to varying radiation attenuating characteristics.

18. The radiation protection panel of claim 15 , wherein the first layer of longitudinal members includes a first radiation attenuating material, and the second layer of longitudinal members include a second radiation attenuating material different from the first radiation attenuating material.

19. The radiation protection panel of claim 1 , wherein the plurality of longitudinal members are attached to the flexible material by a plurality of snap buttons.

20. The radiation protection panel of claim 19 , wherein each snap button includes a ring and a pin for holding the flexible material.

21. The radiation protection panel of claim 19 , wherein the snap buttons include a material more flexible than the flexible material.

22. The radiation protection panel of claim 1 , wherein the plurality of longitudinal members include a plurality of poles.
