Examination of Radiation Absorption Properties of Pb(NO3)2 Doped Wallpapers

Abstract

The harmful effects of radiation on human health have long been recognized. These effects include radiation burns, radiation diseases, shortening of life span, cancer and hereditary disorders. Therefore, the absorption properties and applicability of the material used in radiation shielding are very important. Hence, studies are underway on the development of different types of shielding materials. In this study, radiation absorption properties of lead (II) nitrate Pb(NO3)2 coated wall papers were investigated. The wall papers in different densities (100% precipitated calcium carbonate (PCC), 2.5 g, 5 g, and 7.5 g amounts of Pb(NO3)2) and various thicknesses (0.176-0.236 mm) were prepared and investigated. 4 MeV-energized electrons were applied to the Pb(NO3)2 coated wall papers and measurements were taken with the PTW brand electron detector. Also, theoretical calculations have been done by using WinXCom program. According to the obtained results, these wallpapers' absorption properties increased depending on thickness. Thus, it has been seen that the Pb(NO3)2 coated wallpapers can be used with other materials in radiation shielding.

Özet

Bu çalışmada , 100 TeV proton-proton çarpıştırıcısında, harici tek Higgs üretimi olan pp ®pggp ®pHp süreci üzerinden anormal HZg ve Hgg bağlaşımlarının sınırları incelenmiştir. Sinyal olarak, Higgs bozonunun H®gg ve H®Zg bozounum kanalları ele alınmıştır. Üç farklı akseptans bölgesi 0.015<x<0.15; 0.0015< x <0.5; 0< x <1-ve integre edilmiş luminosite 3000 fb-1 değerleri dikkate alınarak, bu bağlaşımların %95 güvenilirlik düzeyindeki duyarlılık limitleri bulunmuştur. Aynı hesaplar LHC için de yapılmış ve gelecekte kurulması planlanan 100 TeV proton-proton çarpıştırıcısının LHC’ye göre sağladığı iyileştirme yorumlanmıştır.
