    Relationship of Meteorological Variables with the Concentration of Various Tree Pollen Types in Madrid (Spain) by Javier Chico-Fernández, Esperanza Ayuga-Téllez

    Published 2025-01-01
    “…To this end, a multivariate analysis was carried out using Spearman’s linear correlation coefficient between the concentrations in the Madrid atmosphere of six types of tree pollen (Cupressaceae, <i>Olea</i>, <i>Platanus</i>, <i>Pinus</i>, <i>Ulmus</i> and <i>Populus</i>) and each of the six meteorological variables: relative humidity, precipitation, temperature, wind, radiation and insolation. The meteorological parameters most correlated with pollen types, with monthly values, are temperature and insolation, followed by radiation and relative humidity. …”

    Published 2025-01-01
    “…Annual effective ingestion dose from intake of 226Ra, 228Ra, and 40K, for infants (1–2 years), children (7–12 years), and adults (&gt;17 years) ranged from 0.28 to 0.69, 0.32 to 0.82, and 0.12 to 0.30 mSv/year, respectively, and the respective mean values are 0.40 ± 0.11, 0.45 ± 0.14, and 0.17 ± 0.05 mSv/year. 228Ra contributed the largest proportion to ingestion dose (46–67%), indicating potential radiation risk to bones. Lifetime cancer risk ranged from 1.25 × 10−8 to 4.95 × 10−8 for 226Ra, 1.95 × 10−8 to 4.77 × 10−8 for 228Ra, and 5.53 × 10−7 to 1.19 × 10−6 for 40K, with a total mean of 8.96 × 10−7 ± 2.31 × 10−7. …”

    INFINITESIMAL FIELD SIZE HVL OF ISO 4037 NARROW SPECTRUM X-RAYS: SIMULATED RESULTS by Ngoc Thiem Le

    Published 2024-09-01
    “…This work presents Particle and Heavy Ion Transport code System (PHITS) simulated values of HVL and their standard deviations for an infinitesimal radiation field size. The HVL values, calculated from simulated values of air kerma at a detector position for various radiation field sizes, were extrapolated to an infinitesimal field size for different ISO 4037 narrow spectrum X-ray beam qualities at two distances from an X-ray source. …”
