FUN 1 EO: 1.27

1 / 7

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

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

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

2 / 7

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

Increase in genetic mutations

Reduction in cancer risk

Lowering of blood cell counts

Random occurrence of health issues

3 / 7

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

Radiation-induced cataract formation

Cancer development

Genetic mutations

All of the above

4 / 7

Stochastic effects generally occur without:

A threshold level of dose

Increasing severity with increasing dose

Any chance of occurring with low exposure

Any relation to the dose

5 / 7

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

Cataracts and skin burns

Genetic mutations and cataracts

Skin burns and lowering of blood cell counts

Cancer and genetic mutations

6 / 7

What is a characteristic of stochastic effects related to radiation?

There is a threshold level of dose for the effect

Severity of the effect is proportional to the dose

Severity of the effect decreases as the dose increases

Probability of the effect occurring increases with the dose

7 / 7

Which statement is true regarding stochastic effects?

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

They occur by chance and have no established threshold

They have a threshold dose below which no effects will occur

The severity of the effect increases as the dose increases
