Radiation safety based on the sky shine effect in reactor [PDF]

open access: yes, 2020
In the reactor operation, neutrons and gamma rays are the most dominant radiation. As protection, lead and concrete shields are built around the reactor. However, the radiation can penetrate the water shielding inside the reactor pool.

The Emerging Roles of Exosomes as EMT Regulators in Cancer

open access: yesCells, 2020
Epithelial–mesenchymal transition (EMT) causes epithelial cells to lose their polarity and adhesion property, and endows them with migratory and invasive properties to enable them to become mesenchymal stem cells.

Low- and moderate-dose non-cancer effects of ionizing radiation in directly exposed individuals, especially circulatory and ocular diseases: a review of the epidemiology

open access: yesInternational Journal of Radiation Biology, 2021
Purpose There are well-known correlations between high and moderate doses (>0.5 Gy) of ionizing radiation exposure and circulatory system damage, also between radiation and posterior subcapsular cataract.

Organ-Specific Effects of Low Dose Radiation Exposure: A Comprehensive Review

open access: yesFrontiers in Genetics, 2020
Ionizing radiation (IR) is a high-energy radiation whose biological effects depend on the irradiation doses. Low-dose radiation (LDR) is delivered during medical diagnoses or by an exposure to radioactive elements and has been linked to the occurrence of

Analysis of repeated computed tomography scans and cumulative effective dose of patients in a hospital

open access: yesBrazilian Journal of Radiation Sciences, 2023
Computed tomography exams are considered diagnostic imaging exams that generate significant radiation dose to the patient. Justification, optimization, and dose limitation are radiological protection principles used to minimize patient and staff exposure,

Development of Methods to Evaluate Several Levels of Uranium Concentrations in Drainage Water Using Total Reflection X-Ray Fluorescence Technique

open access: yesFrontiers in Chemistry, 2019
As a country's law stipulates the effluent standard uranium concentration in drainage water, the uranium concentration must be determined when drainage water is released from a uranium handling facility, such as the Fukushima Daiichi nuclear power plant.
