key to greater accuracy in internal dose calculation.In order to improve the detection sensitivity of 85Kr, an anti-cosmic HPGe γ spectrometer was established and a specific Marinelli beaker was designed for 85Kr measurement. Comparing to the non-anticoincidence γ spectrum, the integral background counts rate range from 20 to 2400 keV was reduced by a factor of 5.17 using anticoincidence shielding. The minimum detectable activity of 85Kr was 10.5 Bq within 24 h measurement in standard mode and that of 3.99 Bq in anticoincidence mode.

A Firm Double Mattress Balances Comfort and Support Double mattresses that are firm give both comfort and support. It's ideal for back sleepers. Firmer mattresses could help stop the sagging that can cause back pain. They also distribute weight evenly which reduces the pressure on joints and muscles. For back and stomach sleepers, or for people with a larg
