Critical ReadingUnderstanding the textTASK 7 Write a paragraph of about 120 words to summarize the main idea of the text. The population s

37、hould have sufficient understanding of radiation phenomena to secure individual safety as well as democratic decisions. Therefore it is necessary for the communicators of radiation information to be familiar with the laypeoples perceptions of these phenomena. A survey was conducted to examine non-ex

38、perts conceptions of radiation phenomena. The survey revealed incomplete understanding of concepts such as radioactive decay, half-life and absorption of radiation and a lack of differentiation of between radiation and radioactive material. There are indications that the lay understanding of radiati

39、on phenomena is to a large extent formed by mass media and that “school knowledge” of these phenomena is not applied in situations in the real world. Thus, new teaching and information procedures are needed. These should take into account the learners perceptions and should integrate “school knowled
