the effects of a two sievert exposure occurring over a one hour period would be about the same as a one sievert exposure occuring in less than a minute. However, this fact is never considered when using the LNT model to set radiation exposure limits or making estimates of potential health ...
It describes the various effects of radiation and the risk factors associated with stochastic effects. The chapter also explains the various limits recommended for both occupational exposure and general populations and discusses the basic control methods of radiological protection....
radiation hazards. The degree of the radiation hazard varies with different materials and depends on the strength of the ionizing radiation, the half-life, and the amount. Radiation can cause injury after inhalation, ingestion, or direct (external) exposure.[EPA website: Understanding Radiation]...
The yearly effective body, eye, and hand dose were compared with the safety limits of radiation for occupational exposure recommended by the International Commission on Radiation Protection (ICRP). The radiation absorption of various body parts per minute of fluoroscopy was compared among different ...
While T cells are known to be sensitive to high doses of radiation, the increased use of lower radiation doses per fraction, such as those used during hypofractionated radiotherapy, necessitates the need to elucidate the effects of radiation on T cells surviving RT exposure. In this study, ...
Exposure of power MOSFETs to total-dose ionizing radiation causes degra dation in breakdown voltage, transconductance, and leakage current, but the dom inant effect is the large shift in threshold voltage. This work is concerned with the degradation of breakdown voltage caused by ionizing ...
Phosphorylated H2AX is proposed as a biodosimeter for total-body radiation exposure [18]. One day later, whole body irradiation results in lymphocytopenia, neutropenia, and thrombocytopenia [19]. As γ-H2AX, the decrease in numbers of these cells has also been used as a biodosimeter for early...
A literature search has been conducted to identify genes implicated in radiation response using the search queries “radiation genes,”“radiation response genes,” and “radiation signatures” on PubMed. Cited genes comprise those differentially expressed after radiation exposure, genes present in DNA ...
This type of radiation can interact with the human body, leading to significant side effects, which may be favorable to MBS. The ITU establishes limits for general public exposure specified in the national regulations, as such, exposure limits for low and high frequency electromagnetic waves and ...
Health risks from exposure to low levels of ionizing radiation: BEIR VII Phase 2 2006, Health Risks from Exposure to Low Levels of Ionizing Radiation: BEIR VII Phase 2 Enzymatic processing of radiation-induced free radical damage in DNA 1998, Radiation Research Genomic instability induced by ionizi...
