Development of extendable on-line test system for total ionizing dose effect of microprocessor

open access: yesHe jishu, 2022
BackgroundCompared with transistors and small-scale integrated circuits, the total ionizing dose (TID) effect and testing of multifunctional large scale integrated microprocessors are more complex. The difficulty of testing is to analyze the failure mode

Lung Cancer Screening with Low-Dose CT: Radiation Risk and Benefit–Risk Assessment for Different Screening Scenarios

open access: yesDiagnostics, 2022
Lung cancer is a severe disease that affects predominantly smokers and represents a leading cause of cancer death in Europe. Recent meta-analyses of randomized controlled trials (RCTs) have yielded that low-dose computed tomography (LDCT) screening can ...

Ionizing Radiation-Induced Epigenetic Modifications and Their Relevance to Radiation Protection

open access: yesInternational Journal of Molecular Sciences, 2020
The present system of radiation protection assumes that exposure at low doses and/or low dose-rates leads to health risks linearly related to the dose. They are evaluated by a combination of epidemiological data and radiobiological models.

Death of the ALARA Radiation Protection Principle as Used in the Medical Sector

open access: yesDose-Response, 2020
ALARA is the acronym for “As Low As Reasonably Achievable.” It is a radiation protection concept borne from the linear no-threshold (LNT) hypothesis. There are no valid data today supporting the use of LNT in the low-dose range, so dose as a surrogate ...

Radiation dose and protection [PDF]

open access: yesCanadian Medical Association Journal, 2011
All studies should involve the minimum amount of radiation required to provide the required information. Children have an increased risk from radiation exposure because of a longer expected lifespan and increased tissue radiosensitivity.
