The recent developments of second generation PMO have addressed many of the delivery issues and can, therefore, represent an effective strategy for reducing dose levels and frequencies, as well as delivery to nonleaky fibres [ 45, 46].
Since every radiation dose, no matter how low, is assumed to increase risk, and that those risks are additive, this assumption leads to practices such as ALARA (As Low As Reasonably Achievable) where large efforts are made to reduce dose below levels where there is no demonstrable risk, and even to levels below natural background.
[ Based on high and moderate quality randomised controlled trials and the GDG's opinion] If they have achieved sustained and satisfactory levels of disease control with a combination of disease modifying antirheumatic drugs, cautiously try to reduce doses to levels that still maintain disease control.
This data comparison and exchange between hospitals could trigger hospitals, using higher radiation doses for certain CT studies, to reduce their dose levels or to invest in new dose reduction CT technology.
The application of nanoscale delivery systems to herbal remedies may provide remarkable advantages over conventional formulations by improving component solubility, enhancing bioavailability, reducing dose, achieving constant therapeutic levels over an extended time, enhancing stability, and protecting the compounds from physical and chemical degradation [ 10– 10].
Simple geometry Monte Carlo simulations have been used also for calculating regolith shielding properties, and it is shown that a layer of at least 50 cm regolith is needed for significantly reducing the dose levels received by astronauts in a hypothetical lunar habitat.
These diagnostics are integrated inside the Port Plug, a water-cooled stainless steel support structure, which also includes Diagnostic Shielding Modules, designed to provide enough radiation shielding capabilities, to protect the diagnostic systems and to reduce the dose level in the Port Interspace.
They could therefore represent an effective strategy to reduce the dose level and dose frequency for clinical application.
Dose-tracking systems help to reduce CT-dose levels below national DRLs.
