31. A radiation dose of 50 grays, for example. 32. By the end of the mission, the crew experienced an average radiation dose of 1.6 mGy. 33. The sievert is used for radiation dose quantities such as equivalent dose, gray ( Gy ). 34. The ion concentration directly correlated with the radiation dose rate and the composition had non-monotonic consequences. 35. A V / Q scan may still be recommended when a lower radiation dose is required. 36. Under present international guidelines it is assumed that any radiation dose , however small, presents a risk. 37. The radiation dose received from DEXA scans is very low, much lower than projection radiography examinations. 38. A high range radiation dose rate probe was used to screen these metal pieces for radioactivity. 39. While always high, the radiation dose in these belts can increase dramatically during geomagnetic storms and substorms. 40. Diagnosis is also made more difficult, since computed tomography is infeasible because of its high radiation dose .
