1. The average dose rate from background radiation is 360 millirad per year. 2. I . e . format size, slot collimator position, dose rate etc. 3. The " Radiation Dose Rate "-the dose accumulated per year-must be determined first. 4. Civilian dose rates in peacetime range from 30 to 100 �Gy per year. 5. I've been trying to find out the dosing rate for chlorine but I couldn't. 6. At a distance from the x-ray machine, the dose rate decreases by 1 / distance-squared. 7. This gives a steady current proportional to the dose rate the gas is exposed to. 8. Supplied by Siemens-Plessey, this included 92 gamma dose rate monitors located all over the Britain. 9. The ion concentration directly correlated with the radiation dose rate and the composition had non-monotonic consequences. 10. A high range radiation dose rate probe was used to screen these metal pieces for radioactivity.
