Minimizing Radiation to Components
- New recommendations on ionising radiation. Tobias, Jeffrey // BMJ: British Medical Journal (International Edition);10/7/89, Vol. 299 Issue 6704, p879
Focuses on the recommendations on ionising radiation by the Health and Safety Commission in Great Britain. Major concerns on both the public and professional staff on ionising radiation; Impact of government policy on the recommendations; Dosage of annual exposure to radiation on workers.
- U.N. RELEASES REPORT ON IONIZING RADIATION. // National Provisioner;Jan2001, Vol. 215 Issue 1, p30
Focuses on the United Nations scientific committee on the effects of atomic radiation (UNSCEAR). Average dose of background radiation in the environment; Significance of UNSCEAR evaluations on government and organizations as a scientific basis to estimate health risk; Global exposure to natural...
- Considerations concerning the use of counting active personal dosemeters in pulsed fields of ionising radiation. Ambrosi, Peter; Borowski, Markus; Iwatschenko, Michael // Radiation Protection Dosimetry;Jun2010, Vol. 139 Issue 4, p483
Active personal electronic dosemeters (APDs) exhibit limitations in pulsed radiation fields(1), which cannot be overcome without the use of new detection technology. As an interim solution, this paper proposes a method by which some conventional dosemeters can be operated in a way such that,...
- DEPENDENCE OF THE BYSTANDER EFFECT FOR MICRONUCLEUS FORMATION ON DOSE OF HEAVY-ION RADIATION IN NORMAL HUMAN FIBROBLASTS. Yoshitaka Matsumoto; Nobuyuki Hamada; Mizuho Aoki-Nakano; Tomoo Funayama; Tetsuya Sakashita; Seiichi Wada; Takehiko Kakizaki; Yasuhiko Kobayashi; Yoshiya Furusawa // Radiation Protection Dosimetry;2015 Special Isuue, Vol. 166, p152
Ionising radiation-induced bystander effects are well recognised, but its dependence on dose or linear energy transfer (LET) is still a matter of debate. To test this, 49 sites in confluent cultures of AG01522D normal human fibroblasts were targeted with microbeams of carbon (103 keV Î¼m-1),...
- Repair of I-SceI Induced DSB at a specific site of chromosome in human cells: influence of low-dose, low-dose-rate gamma-rays. Fumio Yatagai; Masao Suzuki; Noriaki Ishioka; Hitoshi Ohmori; Masamitsu Honma // Radiation & Environmental Biophysics;Nov2008, Vol. 47 Issue 4, p439
Abstractï¿½ï¿½We investigated the influence of low-dose, low-dose-rate gamma-ray irradiation on DNA double strand break (DSB) repair in human lymphoblastoid TK6 cells. A single DSB was introduced at intron 4 of the TK+ allele (chromosome 17) by transfection with the I-SceI expression...
- MGH customizes CT radiation doses using virtual autopsy. // Medicine on the Net;Jul2011, Vol. 17 Issue 7, p6
The article reports on the testing and customization of computed tomography (CT) protocols on cadavers at Massachusetts General Hospital in Boston, Massachusetts to determine the dosage needed among live patients in as much as half of the national reference levels.
- sievert. Peters, Michael // BMA A-Z Family Medical Encyclopedia;2004, p689
An encyclopedia entry for "sievert" is presented. It refers to a unit for measuring doses of ionizing radiation.
- Cancer and Low Dose Responses in Vivo: Implications for Radiation Protection. Mitchel, R. E. J. // Dose-Response;2007, Vol. 5 Issue 4, p284
The Linear No Threshold (LNT) hypothesis states that ionizing radiation risk is directly proportional to dose, without a threshold. This hypothesis, along with a number of additional derived or auxiliary concepts such as radiation and tissue type weighting factors, and dose rate reduction...
- Interventional Radiology Procedures: Current Issues in Patient Doses and Image Quality Optimization. Compagnone, Gaetano; Fabbri, Emma // Current Medical Imaging Reviews;2009, Vol. 5 Issue 3, p159
Recent technical advances and a renewed interest in protection of patients against the danger of ionizing radiation have prompted new trends in interventional radiology. Therefore this paper presents a review on the state of the art in the field of both radiation doses and image quality...
