Radiation Exposure Dosage Chart: This chart lists ionizing radiation only. Of all the types of non-ionizing radiation, only ultraviolet rays are cancer-causing agents. 10,000 mSv (1,000,000 mrem) as a short-term and whole-body dose would cause immediate illness and subsequent death within...

Space radiation exposure estimates differ from typical terrestrial exposures received during medical diagnostic imaging and cancer radiotherapy. The average effective dose is 0.02 mSv for a chest x-ray and 7 mSv for a computed tomography scan of the chest42, whereas cancer radiotherapy exposures ...
Each output pulse from the GM tube is a count. The counts per second give an approximation of the strength of the radiation field. The GM tube has been calibrated using a cesium-137. The chart is shown inFigure 3. Figure 3. Chart detailing Count Rate vs. Dose Rate ...
The median cumulative effective dose per patient was 6.4 mSv (range, 1.1-127 mSv; mean, 9.26 ± 10.0 mSv). Conclusions: The median cumulative radiation burden from head CT imaging in our cohort equates approximately to a single chest CT scan, well within accepted limits for safe CT imaging...
irradiation. Patients who are referred to RT will receive additional approximately 10 mSv from the additional planning CT scan in DIBH. We expect the potential benefits of DIBH in terms of a reduced dose to the heart and lungs and possibly also other organs will markedly outweigh this ...
Canada’s effective dose limits (for man-made sources of radiation) are defined in the CNSC’s Radiation Protection Regulations as follows: PersonPeriodEffective Dose (mSv) 1. Nuclear energy worker, including a pregnant nuclear energy worker (a) One-year dosimetry period 50 (b) Five-year ...
The median values of the control scans averaged per intervention were 458 [343, 633] (102–1017) mGy*cm for DLP and 1.15 [0.87, 1.35] (0.40–2.20) mSv for the effective dose. A comparison of the age groups yielded significantly (p < 0.001) higher DLP values of the elderly compared to...
