Objectives: The aim of the study was a survey-based assessment concerning parents of children undergoing CT examinations and their knowledge of detailed information about procedures involved in imaging diagnostics.Material and Methods: A statistical analysis of 108 surveys of parents of children undergoing CT studies in the Department of Pediatric Radiology in Poznań, Poland was done, with the use of Statistica software.Results: In result of the evaluation of all subsections of the substantive question number, the majority of answers were incorrect (68-98%). No correlation between the number of CT examinations conducted for a child and the number of correct answers to substantive questions was observed. No correlation between the number of CT examinations conducted for a child and the fact of noting the examination with the use of ionizing radiation down in a child's health certificate was stated. The statistical analysis showed that children of parents who declared that the aim of the CT examination had been explained to them better underwent more of them.Conclusions: Parents are poorly informed about a radiation dose and risk related to a CT examination procedure.

Objectives: To determine the age and the most common circumstances for smoking initiation along with smoking rates and to evaluate smoking trends for secondary and high school students in Poland during 2009 and 2011.Material and Methods: In 2009, a pilot study was conducted in districts of Poland on high school students and their parents. For statistical analysis, correctly completed questionnaires from 999 students and 667 parents were qualified for use. After the pilot study, a nationwide study of secondary school students and their parents was also conducted in 2009. For statistical analysis, correctly completed questionnaires were used from 9360 students and 6951 from their parents. The research tool was a questionnaire developed by the Chief Sanitary Inspectorate. These studies were then compared to the nationwide research study from 2011. Questionnaires were obtained from a survey of 3548 students from secondary schools and 4423 of those from high schools.Results: Smoking initiation usually begins at ages 12-15 years. Rates of secondary school student smoking at least once in their lifetime were about the same level in the surveyed years (2009 - 9%, 2011 - 11%), whereas rates of high school student smoking increased (2009 - 15%, 2011 - 24%). Moreover, 34% of secondary school student smoked less than once a week, whereas in 2009, only 8% of students had done so. For high school students, a 1/2 smoked every day; similar to 2009. Students usually smoked in parks, on streets or any other open space areas.Conclusions: From analyzing the smoking trends over the survey period it can be concluded that the problem of smoking increases with respondent age.
