    Measuring radiation in space with bubble detectors and the effect of radiation on health system of human body
    (American Institute of Physics Inc., 2023) Al-Khafaji, Zainab S.; Radhi, Sabaa S.; Mahdi, Marwah M.; Radhi, Nabaa Sattar; Mareai, Basim M.
    A bubble detector resembles a testing tube or a human fingertip in size and form. It has a material with small liquid droplets in it. When neutrons collide with the droplets, visible bubbles of trapped gas appear almost instantly. The number of bubbles in the surrounding neutron radiation may be measured optically or with a reader, and the number of bubbles reflects the degree of neutron radiation. The gas bubbles may be compressed again and used again. A bubble detector becomes a radiation sensor utilized to assess neutron levels. Neutrons account for 30 percent of the radiations that astronauts encounter in orbit. When protons collide with a spacecraft's shielding, neutrons are produced. To better monitor specific astronauts' neutron exposures throughout space missions, the Canadian Space Agency's Operation Space Medicine (OSM) Group is sponsoring the development of a personal detector device for space usage depending on Canadian bubble dosimeter technology. The current study focuses on mechanisms utilized for detecting radiation, Neutron detectors, and kinds of Neutron detectors, in addition to the effect of radiation on the health system.

    Reducing oil pipes corrosion by (ZN-NI) alloy coating on low carbon steel substrate by sustainable process
    (Taylor's University, 2023) Radhi, Nabaa Sattar; Al-Khafaji, Zainab; Mareai, Basim M.; Radhi, Sabaa; Alsaegh, Ayam M.
    The problem of corrosion is quite risky and costly. There is always the possibility of bridges and buildings collapsing, oil pipelines bursting, chemical plants leaking, and bathroom flooding. Corroded medical implants might result in blood poisoning, corroded electrical connections could start fires and cause other problems, and worldwide air pollution could damage artwork. Corrosion threatens the safe disposal of radioactive waste that should be stored in containers for millennia. This study makes an effort to enhance further the electroplated layer's (Zn-Ni) alloy characteristics. In this study, samples of low-carbon steel are electrodeposited with layers of varying thicknesses of (Zn-Ni) from an alkaline solution throughout various coating times (15, 30, and 60 minutes). The mechanical and corrosion characteristics of the electrodeposits layer are determined using X-ray fluorescence (XRF), which is also utilized to analyse the microhardness and corrosion test results of the (Zn-Ni) deposited layer.
