چکیده
In this bachelor thesis, which is a part of the project RadioRoSo, we examine and analyze waste from Magnox power plants. These power plants were mostly situated in the Great Britain and they were operated between 1956 and 2015. The analyzed waste mainly consists of pieces of Magnox alloy AL80. Springs from alloy Nimonic 80A are also present in the waste and they are considered to be highly radioactive. A main source of the radiation inside the springs is decay of 60Co, 59Ni, and 63Ni. The other radiation comes from surface contamination. The waste is stored under water. This thesis contains a list of particle detectors. We will take a closer look at NaI(Tl) scintillation detector. There will also be introduced semiconductor, scintillation, and ionization detectors. In the end, we will simulate an output of a single NaI(Tl) detector. This detector will be situated over the pieces of magnox, while the discussed springs will lay inside it. Simulations will rather be illustrative because of inaccurate information about the waste.

متن کاملRadioactive in situ Hybridization for Detecting Diverse Gene Expression Patterns in Tissue
Knowing the timing, level, cellular localization, and cell type that a gene is expressed in contributes to our understanding of the function of the gene. Each of these features can be accomplished with in situ hybridization to mRNAs within cells. Here we present a radioactive in situ hybridization method modified from Clayton et al. (1988)(1) that has been working successfully in our lab for ma...
