Objectives

Learning outcomes and competences

By the end of this CT, students should be able to:

• Identify the sources of natural radiation,


• Quantify the radiation in materials of geological origin,


• Establish and characterize the exposure pathways,


• Assess the effects on health and the environment, by calculating doses,


• Framing and interpreting the results obtained in the framework of the applicable legislation,


• Present and communicate in an appropriate way the results of radiation quantification.

Working method

Teaching methods and learning activities

According to the program, classes are of a theoretical-practical nature, consisting of lectures to expose the issues to be addressed, with illustration of concepts, accompanied by examples and presentation of case studies. Students will have the opportunity to apply and test the knowledge acquired by carrying out biweekly assignments in an out-of-class environment.

Evaluation Type

Distributed evaluation without final exam

Assessment Components

Designation	Weight (%)
Trabalho escrito	60,00
Trabalho prático ou de projeto	40,00
Total:	100,00

Amount of time allocated to each course unit

Designation	Time (hours)
Estudo autónomo	28,50
Frequência das aulas	12,00
Total:	40,50

Eligibility for exams

Attendance at least 75% of classes (with mandatory participation in evaluation moments).

Calculation formula of final grade

Two components will be considered:

• T: biweekly work to be done out of the class environment with oral presentation (40%).

• TF: final work with public presentation and report (60%).

Formula for calculating the final grade (NF):

NF = 40% T + 60% TF

According to the GR 02/11/2020, Cap II, art 13, point 1, the final classification will be expressed on an integer numerical scale from 0 to 20 values.

Special assessment (TE, DA, ...)

In these cases, the evaluation will be carried out in a special appeal season via examination in which it will have a weighting of 100%.

Classification improvement

The classification improvement is planned for students who require it.
In these cases, the evaluation will be carried out in a special appeal season via examination in which it will have a weighting of 100%.
