21. After 10 half-lives ( about 53 years ), the dose rate would have decayed to around 10 mSv / hour. 22. After 20 half-lives ( about 105 years ), the dose rate would have decayed to around 10 ?Sv / hour. 23. This was counter to the prevailing assumption of a linear relationship between total dose or dose rate and the consequences. 24. The German IMIS monitoring system uses more than 2000 sensors, measuring gamma dose rate as well as alpha and beta radiation. 25. Flight data will be compared to the results of a novel prediction method taking into account the Enhanced Low Dose Rate Sensitivity. 26. These devices are particularly useful for real-time monitoring of dose where a high dose rate is expected which will time-limit the wearer's exposure. 27. This low dosing rate ensures long fluid refill intervals and minimises the tank's size ( and subsequent obtrusion into vehicle packaging space ). 28. Thus, the width of the fallout pattern for any given dose rate is reduced where the downwind distance is increased by higher winds. 29. One of the recent methods in radiation therapy related to cancer care is called HDR ( High Dose Rate ) internal braky therapy. 30. The device has Total Dose rating of 300Krad, No Latchup at 120 LET and SEU data of 1.34E-10, by using simple SECDED Hamming code.
