It is often the single largest contributor to an individual's background radiation dose, and is the most variable from location to location. (wikipedia.org)
In industrialized countries, Medical imaging contributes almost as much radiation dose to the public as natural background radiation. (wikipedia.org)
In accordance with ICRP recommendations, most regulators permit nuclear energy workers to receive up to 20 times more radiation dose than is permitted for the general public. (wikipedia.org)
Within the last decade, studies have revealed that interventional cardiology and cardiac electrophysiology staff experience increased rates of cancer, skin lesions, cataracts and orthopedic illnesses as compared with their unexposed colleagues, even though they had adhered to international and federal radiation dose limits. (dicardiology.com)
Recent analyses of mortality among atomic bomb survivors have suggested a linear dose-response relationship between ionizing radiation and diseases of the circulatory system for exposures in the range 0-4 Sv. (bioone.org)
Among the remainder, one study found appreciable evidence that exposure to low-dose radiation was associated with circulatory diseases, but five others, all with appreciable power, did not. (bioone.org)
IMRT allows radiation to be focused on hot spots like tumors, where the dose should be high, and spares nearby normal tissue, such as the saliva glands, jawbone and spinal cord, where doses should be low. (beaumont.org)
The benefit of IMRT depends, in part, on the area of the neck that requires high-dose radiation. (beaumont.org)
For the 30 to 40 percent of patients with early stage disease, interstitial high-dose brachytherapy may be combined with external beam radiation. (beaumont.org)
On an outpatient basis, the catheters are connected to a machine that delivers high-dose radiation to the tumor. (beaumont.org)
To date, the most advanced photon beam delivery method is intensity-modulated (IM) radiation therapy (IMRT), which can deliver higher doses of radiotherapy to tumour targets while reducing the dose delivered to selected normal tissues. (nature.com)
hence, one of the concerns of IMRT is that, over time, this exposure of more tissue to low-dose radiation will cause a second malignancy or other unwanted late normal tissue effect. (nature.com)
The radiation targets IMC and SCL, showed a statistically significant trend for an increased risk of stroke with daily fraction dose.A study of 199 patients with BC, examined by coronary angiography, detected a four- to seven-fold increase of high grade coronary artery stenosis in mid and distal left anterior descending artery (LAD), including distal diagonal branch, when comparing women with irradiated left-sided BC to those with right-sided. (kb.se)
Thus, the coronary arteries should be regarded as organs at risk in RT of BC.In a study of 15 BC patients treated with 3D conformal RT, a marked difference in dose distribution in mid and distal LAD between left- and right-sided BC was demonstrated. (kb.se)
Chicago, IL - November 10, 2009 - Clinicians using RapidArc® radiotherapy technology for fast, precise, non-invasive cancer treatments have found that they are able to substantially reduce scatter dose to surrounding healthy tissues, according to several presentations and posters presented this week at the annual meeting of the American Society for Radiation Oncology (ASTRO) in Chicago.

The rem is a unit that describes the equivalent dose, which accounts for the actual biological effect of radiation. (medscape.com)
The rem is calculated by multiplying the absorbed dose (rad) by a quality (Q) factor or the radiation weighting factor (RWF), which reflects the differences in the amount of potential biological effect for each type of radiation. (medscape.com)

Correlation coefficients were calculated separately for 0-, 15-, 20-, and 25-year time-lagged cumulative exposures, total radiation dose (which included medical X-ray dose) and occupational radiation dose. (cdc.gov)
Spearman correlation coefficients between cumulative radiation dose and cumulative asbestos exposures ranged from 0.09 (occupational dose) to 0.47 (total radiation dose), and those between radiation and welding fume from 0.14 to 0.47. (cdc.gov)
These results suggest a fairly large proportion of study population workers were exposed to asbestos and welding fume, that the absolute level of confounding exposure did not affect the risk estimates, and that weak relationships existed between monitored lifetime cumulative occupational radiation dose and asbestos or welding fume. (cdc.gov)
The dose of radiation required in diagnostic imaging falls far below the dose required to induce fetal malformations and miscarriage, and falls exceedingly far below the levels present in radiation disasters such as Hiroshima. (badem.co.za)
The dose of radiation absorbed is measured in milliGrays (mGy) in most parts of the world, apart from North America where it's measured in millirad (mRad). (badem.co.za)
