ABSTRACT
In this paper, the technology used to measure radon concentrations in 8 health centers of Al- Hay city in Wasit, Iraq (December 2019) is one of the types of solid state nuclear track detectors, LR-115. After that, the annual effective dose rate and the excess lifetime cancer risk were calculated for the selected positions in the study area. The detectors were exposed to radon for 45 days, the etched detectors, using an optical microscope, to calculate the track densities, essentially depend on the alpha ray emitted from radon which later on easy converted to radon concentration values. Radon concentration ranges are from (183.47±22.93 to 17.15±2.14) Bq/m3 with a mean of (100.483Bq/m3), which lower than the appropriate radon levels recommended by ICRP "International Commission on Radiological Protection". The readings of "Excess Lifetime Cancer Risk" (ELCR), which ranges from 3.9 ×10-3 to 8.05 ×10-3 with an average value of 0.53% showing that human health is not under risk even it does not develop any lung cancer while human inhale the radon.

ABSTRACT
Numerous fungi can cause a variety of diseases in both humans and animals. Some are pathogenic or opportunistic: meaning this fungi cause disease when they find an opportunity to do so, such as when immunity is low or the right conditions are present for the fungus to grow. Fungi sinusitis is one of disease. This study involved the isolation, diagnosis, and analysis of fungi that cause sinusitis in a number of individuals who were diagnosed with the disease by a medical professional. Fungi were grown from patient samples on plates, and the fungus's shape on the dish was used to aid in the diagnosis process. beneath an optical microscope. Studies have also looked at the connection between this fungal infection and a number of variables, such as the patient's age, gender, and the chronic disease.

ABSTRACT
Background: Low Back pain [LBP] is an extremely common human phenomenon. It is a significant source of long-term disability and work absence and accounts for approximately 80% for the total costs of back pain care. Work related musculoskeletal disorders and in particular low back pain, pose a major health and socioeconomic problem in modern society. Prolonged standing has become a major contributing factor for low back pain and traffic duty of police officers is one of the most common occupations for exposure to a prolonged standing for about four hours a day. Objective: To determine the prevalence of low back pain and its association with standing among traffic policemen. Methodology: The six months study was conducted on 180 subjects after obtaining the permission from the Assistant Commissioner of Police, Traffic, Bhubaneswar. These subjects were divided in to two groups of 90 each. The Group-A consisted of traffic policemen those were involved in standing for at least four hours a day and Group-B consisted of professionals from the same department other than traffic policemen those were not involved in standing activities most of the time during their duty hours. Results: There is an approximately perfect positive correlation between the levels of pain and disability index in Group-A and Group-B with r-value of 0.9926 and 0.9785 respectively. There is a significant difference between the levels of pain in Group-A and Group-B with t-value of 6.72 (p≤0.001). There is a significant difference between the levels of disability index in Group-A and Group-B with t-value of 6.33 (p≤0.001). Standing is associated with pain and disability index in Group-A more than Group-B with chi-square value of 14.4 (p≤0.001). The prevalence of pain and disability index in Group-A was 47% and in group-B, it was 20%. Conclusion: The study showed that low back pain is highly prevalent among traffic policemen and standing is significantly associated with low back pain.
