Abstract
Radiation is an energy that come from unstable atoms or machines can produce it and that travels through the air. While there are many types of radiation, they all fall into one of two classes: ionizing or non-ionizing. Non-ionizing radiation is all around us in forms as diverse as radio waves and visible light and we use many of those forms in our daily life. Ionizing radiation is used in healthcare facilities and manufacturing settings in healthcare, radiation is also used in a wide variety of diagnostic devices, such as CT scanners, and concentrated for the treatment of tumours and cancers (Safety management group., 2018).
In service training program is a planned learning experience provided by the employing agency for employee. The American Society for Health Care Education and Training added that it is instruction relating to the education necessary to perform job related duties. The purpose of teaching is to help health team to acquire, retain and he able to use knowledge, understand, analyze, synthesize and evaluate, achieve skills. Thus helping the organization to achieve its goals (Sajjadnia et al., 2019).
The present study aimed to increase the knowledge and practices of nurses and technicians about radiation safety measures at Main Assuit University Hospital. A quize -experimental research design was used in this study. This study was conducted at Main Assuit University Hospital in Diagnostic radiation, oncology and nuclear medicine departments. Random sample was used to include nurses and technicians. The sample size include 50% of the number of nurses and technicians were randomly selected. The final sample size was 105 divided to 25 nurses and 80 technicians
Two tools were used in this study the first was the self administrative questionnaire sheet was developed by researchers to collect information from the participants. It includes two parts: first part was designed to assess personal characteristics of nurses and technicians such as sex, age, marital status, department, education level, years of experience and occupation, second part was designed to assess nurses and technicians’ knowledge about radiation such as: definition, types, causes, uses, and effect of radiation on cells and the second tool observation check-list to assess nurses and technicians’ practice of using radiation safety measures during their work. It was Includes protective measures as, wearing gloves , suitable mask , applying gown & apron and hand washing .The data collection consumed about 11 months ( 4 months )for preparation for training program (from August 2020 to November 2020) and 7 months for data collection ( from December2020 to June2021).
The main results of the present study were:
1- The study findings Showed that 38.1 % of the studied nurses and technicians aged ˂ 30 years in addition, 67.6% of them had technical institute. While 51.4% had job experience less than 10 years .It was noticed that only 7.6% of studied nurses and technicians had attending training courses about radiation
2- Regarding periodic medical examination and exposure to occupational diseases. It was observed that 21.0% of studied nurses and technicians were done periodic medical examination. While 36.2% of them suffering from diseases resulting from working. Also 78.9% and 71.0% of them complained from blood diseases and eye disease respectively. Also 10.5% of them complained from genital glands diseases.
3- The study cleared that there were statistical significant differences between periodic medical examination, frequency of examination and exposed diseases resulting from working in department of radiology with level of education p-value=0.000, 0.005 and 0.000 respectively
4- The study cleared that there were statistical significant differences between diseases resulting from working in department of radiology with years of experience p-value= (0.000). Also there were statistical significant differences between studied working experience and blood diseases p-value 0.053. Also showed that the most exposure participants were had more than 20 years of experience that exposed to heart disease, eye diseases, and skin diseases 84.2%,78.9%and 52.6% respectively.
5- The study cleared that there were statistical significant differences in pre, post and follow up tests with improvement in their knowledge and practice occured in post test after implementation the program. In follow up test after three months later some decline occured in their knowledge and practice but still better than pre test.
