Synthetic Biology- Precautionary Principle. 1. “. When an activity raises threats of harm to human health or the environment, precautionary measures should be taken even if some cause and effect relationships are not fully established scientifically. In this context the proponent of an activity, rather than the public, should bear the burden of proof. The process of applying the Precautionary Principle must be open, informed and democratic and must include potentially affected parties. It must also involve an examination of the full range of alternatives, including no action. Last lecture. Radiation Units. Shortly after the discovery of x-rays in 1885 by Professor Roentgen scientists began to notice the harmful effects of exposure to this radiation. There were many years before people realized how dangerous x-rays and other radiation could be. Quite number of pioneer radiologists suffered severe injuries, and some even died, as a result of prolonged exposure to dangerously high intensities of X-rays. These early workers in the field had no means of measuring the harm caused by radiation accurately and depended on unreliable effects such as the degree of skin reddening caused by the exposure, or on timing the exposure from a certain type of X-ray machine to establish . in A deep sea mining context.
