{"cited_by_count":253330,"description":"This cluster of papers focuses on the development and characterization of materials and techniques for shielding against radiation, including gamma rays, X-rays, and neutrons. It covers topics such as attenuation coefficients, mass attenuation, effective atomic numbers, and the use of borate glasses and polymer composites for radiation shielding. The cluster also explores the application of Monte Carlo simulations in evaluating radiation shielding properties.","display_name":"Radiation Shielding Materials Analysis","domain_id":"3","external_ids":{"openalex":"https://openalex.org/T12299","wikipedia":"https://en.wikipedia.org/wiki/Radiation_shielding"},"field_id":"25","id":"T12299","keywords":[{"display_name":"radiation shielding","id":"radiation-shielding","score":0.3431,"url":"https://openalex.org/keywords/radiation-shielding"},{"display_name":"gamma-ray shielding","id":"gamma-ray-shielding","score":0.7997,"url":"https://openalex.org/keywords/gamma-ray-shielding"},{"display_name":"mass attenuation coefficient","id":"mass-attenuation-coefficient","score":0.7985,"url":"https://openalex.org/keywords/mass-attenuation-coefficient"},{"display_name":"half-value layer","id":"half-value-layer","score":0.6624,"url":"https://openalex.org/keywords/half-value-layer"},{"display_name":"gamma-ray attenuation","id":"gamma-ray-attenuation","score":0.3513,"url":"https://openalex.org/keywords/gamma-ray-attenuation"},{"display_name":"linear attenuation coefficient","id":"linear-attenuation-coefficient","score":0.6827,"url":"https://openalex.org/keywords/linear-attenuation-coefficient"},{"display_name":"effective atomic number","id":"effective-atomic-number","score":0.5504,"url":"https://openalex.org/keywords/effective-atomic-number"},{"display_name":"neutron shielding","id":"neutron-shielding","score":0.4522,"url":"https://openalex.org/keywords/neutron-shielding"},{"display_name":"radiation shielding materials","id":"radiation-shielding-materials","score":0.7918,"url":"https://openalex.org/keywords/radiation-shielding-materials"},{"display_name":"X-ray attenuation","id":"x-ray-attenuation","score":0.2169,"url":"https://openalex.org/keywords/x-ray-attenuation"},{"display_name":"tenth value layer","id":"tenth-value-layer","score":0.9153,"url":"https://openalex.org/keywords/tenth-value-layer"},{"display_name":"buildup factors","id":"buildup-factors","score":0.7375,"url":"https://openalex.org/keywords/buildup-factors"},{"display_name":"X-ray shielding","id":"x-ray-shielding","score":0.6885,"url":"https://openalex.org/keywords/x-ray-shielding"},{"display_name":"radiation attenuation","id":"radiation-attenuation","score":0.3485,"url":"https://openalex.org/keywords/radiation-attenuation"},{"display_name":"neutron attenuation","id":"neutron-attenuation","score":0.358,"url":"https://openalex.org/keywords/neutron-attenuation"},{"display_name":"reactor shielding","id":"nuclear-reactor-shielding","score":0.3438,"url":"https://openalex.org/keywords/nuclear-reactor-shielding"},{"display_name":"shielding materials","id":"shielding-materials","score":0.3444,"url":"https://openalex.org/keywords/shielding-materials"},{"display_name":"fast neutron removal cross-section","id":"fast-neutron-removal-cross-section","score":0.9167,"url":"https://openalex.org/keywords/fast-neutron-removal-cross-section"},{"display_name":"exposure buildup factor","id":"exposure-buildup-factor","score":0.9357,"url":"https://openalex.org/keywords/exposure-buildup-factor"},{"display_name":"concrete shielding","id":"concrete-shielding","score":0.3804,"url":"https://openalex.org/keywords/concrete-shielding"},{"display_name":"XCOM","id":"xcom","score":0.8073,"url":"https://openalex.org/keywords/xcom"},{"display_name":"photon attenuation","id":"photon-attenuation","score":0.4386,"url":"https://openalex.org/keywords/photon-attenuation"},{"display_name":"lead-free radiation shielding","id":"lead-free-radiation-shielding","score":0.8978,"url":"https://openalex.org/keywords/lead-free-radiation-shielding"},{"display_name":"effective electron density","id":"effective-electron-density","score":0.7943,"url":"https://openalex.org/keywords/effective-electron-density"},{"display_name":"radiation protection efficiency","id":"radiation-protection-efficiency","score":0.9661,"url":"https://openalex.org/keywords/radiation-protection-efficiency"}],"legacy_keywords":["Radiation Shielding","Attenuation Coefficients","Gamma-Ray Shielding","Nuclear Radiation","Mass Attenuation","Monte Carlo Simulation","Borate Glasses","Polymer Composites","Effective Atomic Numbers","X-ray Absorption"],"openalex_id":"https://openalex.org/T12299","source_created_date":"2024-01-23T15:27:13","source_updated_date":"2026-10-17T03:02:00","subfield_id":"2505","url":"/topics/T12299","works_api_url":"https://api.openalex.org/works?filter=topics.id:T12299","works_count":26801,"label":"Radiation Shielding Materials Analysis","provider":"openalex","revision":"8062284b6a967dcc","taxonomy_revision":"f050b5d4780b1289","title":"Radiation Shielding Materials Analysis","kind":"topic-directory","aeo_cohort":"topic-directory","catalogue_revision":"f050b5d4780b1289","numeric_address":"38350983897735327","address_version":"morton4x16-v1","coordinates":[3,25,2505,12299],"answer_status":"Directory metadata;
