1) From http://www.ncbi.nlm.nih.gov/pubmed/21123642 and then from http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2996147/: "This review provides a practical overview of the excess cancer risks related to radiation from medical imaging...Radiation-induced risk is more controversial at doses between 10 and 100 mSv, the dose range relevant to medical imaging and in particular CT. A single CT of the abdomen may have a dose of around 10 mSv, and patients who undergo multiple CTs or a single multiphasic CT fall into this dose range. Nuclear cardiology examinations also typically fall in this dose range. Some investigators suggest that direct epidemiological data from atomic bomb survivors and nuclear industry workers indicate increased cancer risk in this dose range..."
2) "Although ionizing radiation has long been recognized as a potential carcinogen capable of introducing harm to patients, the long-term derived benefits have been accepted because of the diagnostic and therapeutic benefits derived from its use. With the increased utilization of high-dose ionizing radiation examinations (such as multidetector computed tomography), it is essential that the medical community create data-driven methodologies to quantify risk in objective terms, develop community-wide radiation standards and "best practice" guidelines (evidence-based medicine), develop new technologies and applications to proactively minimize radiation dose while maintaining quality, and create accountability measures for all pertinent stakeholders."http://www.ncbi.nlm.nih.gov/pubmed/19643383.
3)About Computer tomography [CT scans aka cat scans]: " First, it is important to understand the patterns of use and increasing application of CT, particularly multidetector CT. In addition, it is helpful to be familiar with measures of radiation pertinent to CT and the doses provided by this modality. This foundation then provides a context in which to discuss the issue of low-dose radiation and cancer risk as well as potential changes in CT practice guidelines and regulation. "http://www.ncbi.nlm.nih.gov/pubmed/17411538.
4) "This analysis shows that paediatric CT scans are adjusted according to the patient's age in most of the routine CT examinations. This indicates increased awareness regarding radiation risks associated with CT. However, high tube current settings are still used in younger patient groups, thus, optimisation of paediatric CT protocols and implementation of current guidelines, such as age-and weight-based scanning, should be recommended in daily practice."http://www.ncbi.nlm.nih.gov/pubmed/22970059.
5) "Computed tomography (CT) has been recognised as the most widely used imaging technique in both adults and children, owing to technological developments, especially with the recent innovations in multislice CT. This has resulted in an increase in the use of CT examinations in children younger than 15 years of age in developed countries. The increasing use of paediatric CT in clinical practice has raised concerns regarding the potential risk of radiation-induced malignancy. This is because CT examinations deliver a much higher radiation dose than conventional radiographic techniques. Children are more sensitive to radiation exposure than adults and have a longer time ahead of them to manifest radiation-induced effects and injuries. Therefore, it is of paramount importance to reduce or minimise the radiation dose to children when choosing CT as the major imaging modality for diagnostic purposes."http://www.ncbi.nlm.nih.gov/pubmed/20658103.
6) The topic of how to treat a person who was over-radiated has 1155 results by searching :http://www.ncbi.nlm.nih.gov/pubmed/?term=how+to+treat+over+radiation+with+scans includes DCT scans, MRIs, CT scans, SRT scans, FDG-PET scans .
If this causes people to question those annual exposures for so-called diagnostic tests that involve xrays or radiation [including scans] then it has accomplished the goal.
