6.1 (Historical Patterns in Techological Evolution)

Technology: way of interactions of humans and their societies with the world

Physical, chemical and biological world

A lot of technology changes trough the years

REAL CHANGES

Industrial Revolution

Agrarian communities to urban center.

Agrarian activities to manufacturing,

Technology evolution grew up in the last centuries

6.2 (Aproaches to Risk)

Risk ("probability to suffer a harm from a hazard")

Enviromental Risks: impacts to human health or enviroment.

Also includes: economic, social, cultural and psychological impact.

2 dimensions: objective and subjective

Objective: quantitative, stadistics

Subjective: related to perspectives

Risk Analysis

1. Assessment

2. Communication

3. Management

6. 3 (Risk Assessment)

Highly Quantitative - expressed mathematically

Statistical/Quantify the risk

5 stages:

1. Hazard ID

2. Delivered dose

3. Probability of a negative effect as a result of the dose (one of the great challenge)

4. Determination of the exposed population

5. Calculation of the Total Risk Impact

CRA MODELS: differente categories of risks.

1. Damage to biological systems.

2. Negative effects to the enviroment

3. Damage to fundamental planetary systems

6.4 (Risk Communication)

Result of the assessment is communicated to interested parts.

Important to have an accurate communications

Consider everyone´s goals and motivation in order to communicate in the best way - No misinterpretations

6.5 (Risk Management)

Action taken by the org. to minimize the risk or fight it.

Last step - Make decisions of policies or regulatory actions that must be taken

The decision must be based on the quantitative analysis but it is a subjective decision based on the perspective of those involved in making it
