FUN 1 EO: 1.27

1 / 7

What distinguishes non-stochastic (deterministic) effects from stochastic effects?

Non-stochastic effects occur by chance and are independent of the dose

Non-stochastic effects vary with the dose and have a threshold

Non-stochastic effects always lead to cancer and genetic effects

Non-stochastic effects have no chance of occurring below a certain dose

2 / 7

Two examples of stochastic effects in the context of radiation protection are:

Genetic mutations and cataracts

Cancer and genetic mutations

Cataracts and skin burns

Skin burns and lowering of blood cell counts

3 / 7

What is a common effect that could result from deterministic (non-stochastic) effects due to radiation exposure?

Reduction in cancer risk

Increase in genetic mutations

Random occurrence of health issues

Lowering of blood cell counts

4 / 7

Stochastic effects generally occur without:

Any chance of occurring with low exposure

Increasing severity with increasing dose

Any relation to the dose

A threshold level of dose

5 / 7

What is a characteristic of stochastic effects related to radiation?

Severity of the effect decreases as the dose increases

There is a threshold level of dose for the effect

Severity of the effect is proportional to the dose

Probability of the effect occurring increases with the dose

6 / 7

In the context of radiation, which of the following is an example of a non-stochastic effect?

Radiation-induced cataract formation

Genetic mutations

All of the above

Cancer development

7 / 7

Which statement is true regarding stochastic effects?

They have a threshold dose below which no effects will occur

They occur by chance and have no established threshold

The severity of the effect increases as the dose increases

The effects typically result from the collective injury of a few cells
