Over the past few years, we've seen some of the most innovative research to address this challenge, and this contest is designed to further encourage new ideas and reinforce our commitment to collaborating with clinicians and scientists around effective radiation
dose management programs.
Each time a pediatric patient undergoes a procedure with a radiation-dependent modality, the effective radiation
dose is added to the total effective exposure.
6 minutes at 30,000 feet receive the same amount of UV-A [cancer-causing] effective radiation
as that from a 20-minute tanning bed session," the authors write in the paper.
Core products revolve around less-invasive image guided surgery technology, more accurate and effective radiation
therapy, and integration through planning and collaboration systems that bring patient data and physicians together.
We think the most important single take-away point for concerned passengers is to keep an appropriate perspective: the effective radiation
dose received by a passenger during screening is comparable to what that same passenger will receive in 12 seconds during the flight itself or from two minutes of natural radiation exposure," he added.
The effective radiation
dose (ED) was calculated using the following formula: (ED=DLP x Conversion factor (0.
The government's initial threshold for evacuation of 20 millisieverts per year "conveyed the message that effective radiation
doses up to 20 millisievert per year was safe".
It must be noted that in a photocatalytic process, the catalyst must be activated firstly by the effective radiation
, then the maximum contact must occur between the activated catalyst and the organic compound.
The key to safe, effective radiation
therapy is often to maximize the dose to the tumor, and to minimize the dose to critical structures, or organs-at-risk.
Complex shading layers are treated as individual layers with effective radiation
properties, but with assumed uniform layer temperature (no thermal resistance of shading layer).
The only significant factors affecting prostate-specific antigen (PSA) failure at 5 years were use of hormone therapy, a biologically effective radiation
dose over 150 Gy, initial PSA level, and Gleason score.
The Agriculture Research Service of the USDA has conducted numerous studies on establishing effective radiation
doses for reducing pathogens in many different foods, including leafy greens such as spinach.
