222Radon carcinogenesis: Risk estimation in different working environments

open access: yesJournal of Radiation and Cancer Research, 2021
Background: Occupational exposure to radon in working environments should be considered as chronic because the subjects involved undergo the effect due to the ionizing radiation from the same gas and decay products.

Carcinogenic and Cocarcinogenic Effects of Radon and Radon Daughters in Rats.

open access: yesEnvironmental Health Perspectives, 1994
It has been previously established that lung cancer could be induced in rats by exposure to radon and radon daughters. Although the oat-cell carcinomas that are common in humans were not found in rats, other histological types of lung carcinomas, especially squamous cell carcinomas and primitive lung adenocarcinomas, were similar to those observed in ...

Feasibility of convection‐enhanced delivery of unlabeled 225Ac for glioblastoma: Transport, dosimetry, and clonogenic survival modeling

open access: yesMedical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Glioblastoma (GB) is an aggressive primary brain tumor with local recurrence rates exceeding 90% and a five‐year survival rate of approximately 5%. Standard treatments such as surgical resection, external beam radiotherapy (EBRT), and chemotherapy often leave residual tumor cells that are resistant to therapy.

Tailoring Phonon‐Driven Responses in α‐MoO3 through Isotopic Enrichment

open access: yesAdvanced Materials, Volume 38, Issue 39, 13 July 2026.
ABSTRACT The implementation of polaritonic materials into nanoscale devices requires selective tuning of parameters to realize desired spectral or thermal responses. One robust material, α‐MoO3, an orthorhombic crystal boasting three distinct phonon dispersions, provides three polaritonic dispersions of hyperbolic phonon polaritons (HPhPs) across the ...
