1. An apparatus, comprising:a curtain configured to block through passage of electromagnetic radiation, wherein said curtain is a unitary body made of a combination of a polymer material and a particulate material uniformly dispersed therein, the curtain having a length extending from a mounting end to a distal end, wherein a thickness of the curtain tapers along said length. 2. The apparatus of claim 1, where the curtain includes a mounting feature integrated into said mounting end. 3. The apparatus of claim 2, wherein mounting feature is an integral mounting bead. 4. The apparatus of claim 3, wherein the integral mounting bead has a circular cross section. 5. The apparatus of claim 2, wherein mounting feature is an opening extending through the curtain at said mounting end. 6. The apparatus of claim 2, wherein mounting feature is a bar encapsulated by the unitary body. 7. The apparatus of claim 1, wherein the thickness tapers from a first thickness adjacent the mounting end to a second thickness adjacent the distal end, and the first thickness is thicker than the second thickness. 8. The apparatus of claim 1, wherein the thickness tapers from a first thickness adjacent the mounting end to a second thickness adjacent the distal end, and the second thickness is thicker than the first thickness. 9. The apparatus of claim 1 wherein the polymer material is a urethane and the particulate material is at least one of Tungsten powder and Barium sulfate. 10. The apparatus of claim 1, wherein the polymer material is a thermosetting polymer. 11. The apparatus of claim 1, wherein the curtain includes opposed surfaces, and wherein at least one surface of the opposed surfaces includes a surface texture. 12. The apparatus of claim 11, wherein the surface texture is configured to reduce a surface area of the curtain which is contacted by an item displacing the curtain. 13. The apparatus of claim 11, where the surface texture is formed by a protrusion on said at least one surface of the opposed surfaces. 14. The apparatus of claim 11, where the surface texture is formed by an indentation in said at least one surface of the opposed surfaces. 15. The apparatus of claim 1, wherein the curtain includes a plurality of flaps, each flap extending from the mounting end to the distal end. 16. The apparatus of claim 1, further comprising a curtain suspending member configured to engage the mounting end of the curtain. 17. The apparatus of claim 1, further comprising an electromagnetic exposure station including an entrance opening and an exit opening, wherein said curtain is suspended across one of said entrance opening and exit opening. 18. An apparatus, comprising:a curtain configured to block through passage of electromagnetic radiation, wherein said curtain is a unitary body made of a combination of a polymer material and a particulate material uniformly dispersed therein, the curtain having opposed surfaces, and wherein at least one surface of the opposed surfaces includes a surface texture. 19. The apparatus of claim 18, wherein the surface texture is configured to reduce a surface area of the curtain which is contacted by an item displacing the curtain. 20. The apparatus of claim 18, where the surface texture is formed by a protrusion on said at least one surface of the opposed surfaces. 21. The apparatus of claim 18, where the surface texture is formed by an indentation in said at least one surface of the opposed surfaces. 22. The apparatus of claim 18, where the curtain includes mounting end and a mounting feature integrated into with said mounting end. 23. The apparatus of claim 22, wherein mounting feature is an integral mounting bead. 24. The apparatus of claim 23, wherein the integral mounting bead has a circular cross section. 25. The apparatus of claim 22, wherein mounting feature is an opening extending through the curtain at said mounting end. 26. The apparatus of claim 22, wherein mounting feature is a bar encapsulated by the unitary body. 27. The apparatus of claim 18, wherein the polymer material is a urethane and the particulate material is at least one of Tungsten powder and Barium sulfate. 28. The apparatus of claim 18, wherein the polymer material is a thermosetting polymer. 29. The apparatus of claim 18, wherein the curtain includes a plurality of flaps, each flap extending from a mounting end of the curtain to a distal end of the curtain. 30. The apparatus of claim 18, further comprising a curtain suspending member configured to engage a mounting end of the curtain. 31. The apparatus of claim 18, further comprising an electromagnetic exposure station including an entrance opening and an exit opening, wherein said curtain is suspended across one of said entrance opening and exit opening.
