The invention consists of radiation shielding materials for shielding in the most structurally robust combination against galactic cosmic radiation (GCR), neutrons, and solar energetic particles (SEP). Materials for vehicles, space structures, habitats, landers, rovers, and spacesuits must possess functional characteristics of radiation shielding, thermal protection, pressure resistance, and mechanical durability. The materials are tailored to offer the greatest shielding against GCR, neutrons, and SEP in the most structurally robust combination, also capable of shielding against micrometeoriod impact. The boron nitride nanotube (BNNT) is composed entirely of low Z atoms (boron and nitrogen). Some of the materials included in this invention are: boron nitride (BN) platelets, hot pressed BN, BNNT, BN particle containing resins, BN nanofiber containing resins, carbon fiber reinforced BN containing resins, BNNT containing resins, and hydrogenated BN and BNNT, hydrogen stored BN and BNNT, high hydrogen containing polymer or ceramic matrices, and a combination of these.

To provide patient shielding of non-treatment areas bordering a treatment zone of the patient during radiation therapy, a shield device may be located on the patient. The shield device has a plurality of interconnected and overlapping elements, e.g. in a scale maille arrangement, that forms a conformal sheet that can be laid over the shielded portion of the patient, e.g. over the contralateral breast during breast cancer treatment. The edge of the scale maille sheet is substantially configurable and can be made to conform to the field edge of the treatment zone on the patient.

Provided is a device for measuring a micro flow rate. The device includes a container having an internal space for containing a fluid flowing therein and an inflow line and an outflow line formed in communication with the internal space, a fluid level gauge configured to sense whether a level of a fluid collected in the container rises to a predetermined height to conduct or block flow of an electric current, a control valve disposed in the outflow line and configured to open or close the outflow line according to a state in which the control valve is electrically connected to or disconnected from the fluid level gauge such that the outflow line is opened or closed according to a change in the fluid level; and a control unit configured to calculate a micro flow rate of the fluid collected in the container using information acquired from at least one of the fluid level gauge and the control valve.

A method for producing a lead-free X-ray shielding material using a bismuth halide compound is provided, the method including a first step of producing porous PDMS (Polydimethylsiloxane); a second step of producing a mixed solution of the bismuth halide compound and THF; and a third step of immersing the porous PDMS into the mixed solution such that the bismuth halide compound is loaded into the porous PDMS to produce a bismuth halide compound-PDMS composite material.
