The total dose is determined by the solution of paragraph 4. Organizing
work should be also define the start time and duration of work for each work shift.
For this you can use the methodology for solving the paragraph 5.
The results of calculations are entered into the table for analysis.
In general conclusions, analyzing the results of solving paragraphs, should
be note:
- in what zone of contamination there may be an object of economic activity
and time of beginning of contamination;
- preliminary measures to protect man in the area of contamination;
- in what zone of contamination the object was at the measured level of
radiation;
- which dose of radiation can man get during the term of work on the
contaminated territory, measures to protect people in real conditions.

4 TASK OF CLASS
4.1 Before meeting on class, students should study basic theory of risk
assessment of radiological hazards. All students are expected to come to class alert
and ready to participate in discussion.
4.2 Students in the classroom at the request of a teacher give answers on the
questions.
4.3 Then the students should solve the tasks (should classify objects and
medical procedures as using or producing ionizing radiation, non-ionizing
radiation, or both; determine parameters of radiation) acording to the variant given
by teacher. They may use references [1] and theoretical data from basic theory.
Task 8.1: Pretest Activity: Ionizing, Non-Ionizing, or Both?
The following objects and medical procedures produce or use radiation.

Your task according to Figure 8.5 is to classify items 1-16 as using or producing
ionizing radiation, non-ionizing radiation, or both. Place an “” in the column that
correctly identifies the type of radiation produced or used for each. Finally, circle
the picture of those that emit particle radiation.
