Severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) is a single‐stranded RNA virus that causes many diseases such as respiratory diseases, cardiovascular diseases, and gastrointestinal diseases. Although it has been shown that the angiotensin‐converting enzyme 2 receptor, which has a high affinity for the SARS‐CoV‐2 is mostly expressed in the lungs, it is also expressed especially in the cells of the testicular tissue. Although there are studies showing the effect of SARS‐CoV‐2 on spermatogenesis, the effects of COVID‐19 on sperm count, motility, and morphology are still unclear. The aim of this study is to investigate changes in sperm quality in men who had recovered and never had COVID‐19, therefore semen samples were analyzed from all individuals in the patient and control groups aged 20–50 years who agreed to participate in the study and voluntary in SBU Ministry of Health Adana City Training and Research Hospital. (Toros University Ethics Committee Decision Number: 1433, Date: April 15, 2021) (Adana Provincial Health Directorate Ethics Commission Decision dated May 27, 2021/5). Two groups were selected (100 men had and recovered from COVID‐19, and 100 men never had COVID‐19) spermiograms from both groups were analyzed in accordance with the World Health Organization standards. The sperm concentration of the COVID‐19 negative group was significantly higher than those in the COVID‐19 positive group. No statistically significant difference was detected between the groups for sperm motility and morphology. ​It was observed that men with COVID‐19 had decreased sperm concentrations suggesting that COVID‐19 may have a negative effect on male fertility. However, in the long term, more comprehensive studies with a large sample size are needed to understand better the changes in sperm concentration.

People are exposed to both internal and external radiation from the natural radiation sources. For this reason, studies determining the natural radiation level are made to detect the effects of radionuclides, that constitute the natural radiation sources, on the environment and especially the effects of radiation on people and on biological systems. The most common radiation sources are 238 U, 226 Ra, 232 Th and 40 K radioisotopes. In this study, in the samples of the rock and soil acquired from Amasya Şeyhcui Region, the activity concentrations of 226 Ra, 232 Th and 40 K are determined by using NaI (Tl) detector with gamma spectrometer and are compared with the limit values.

The coronavirus disease-19 (COVID-19) pandemic became the greatest public health challenge globally. In our study, it was aimed to determine the antibody levels in the third month after the COVID-19 infection and the symptoms that continued until the third month from the onset of the infection. One hundred people who applied to Tarsus State Hospital with the suspicion of COVID-19 and were positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection by realtime reverse transcriptase-polymerase chain reaction were included. We collected serum samples from individuals, who were 3 months postinfection, and tested them in anti-SARS-CoV-2 Quanti-Vac ELISA IgG kit coated with recombinant S1 antigen for testing SARS-CoV-2 antibodies. Antibody levels were found to be higher in those aged ≥55 years, nonsmokers, those with comorbidities, and those who were hospitalized. The four most common symptoms that individuals initially encounter; are weakness, muscle and joint pain, loss of taste and smell, and cough. In 3 months after COVID-19 infection, the most common four symptoms are; muscle and joint pain, insomnia, fatigue, and other problems were determined. In conclusion; more research is needed to determine threshold levels of serum antibodies that could prevent reinfection of SARS-CoV-2.

Ionizing radiation is commonly used in diagnostic and therapeutic applications in medicine. Therefore, both staff and patients are exposed to the biological influence of radiation. Biological effects and damages are proportional to the irradiation.In this study the radiation dose to human in the patient room and the technician room at computed tomography and X-ray units were measured and compared for different situations.

This study was carried out to evaluate the radiation awareness of the students who receive education in various fields in hospitals in the future and to draw attention to this subject. It is very important for the health of the students who will work in the field of radiation to be aware of radiation as it is their profession. At the same time, even if the students of other departments will not be able to work, they will radiation services for diagnosis or treatment at some point in their lives. For this reason, the study was conducted for health care providers and service recipients in the future. It was applied to all associate degree program students at Toros University Health Service Vocational School between November-December 2021. Thus, the difference between the Medical Imaging While there was a significant difference in terms of X-ray knowledge level (t=7,470; p=0.000), awareness (Z=-3.406; p=0.001), awareness of radiation protection (64; p=0.000), there was a statistically significant difference according to age and gender no difference was detected. Techniques for students who receive training on radiation and the students in other programs that are not given information about radiation in the training content have been revealed.
