FUN 1 EO: 1.27

1 / 7

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

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

Non-stochastic effects always lead to cancer and genetic effects

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

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

2 / 7

Stochastic effects generally occur without:

Increasing severity with increasing dose

Any relation to the dose

Any chance of occurring with low exposure

A threshold level of dose

3 / 7

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

All of the above

Cancer development

Genetic mutations

Radiation-induced cataract formation

4 / 7

Which statement is true regarding stochastic effects?

They occur by chance and have no established threshold

They have a threshold dose below which no effects will occur

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

The severity of the effect increases as the dose increases

5 / 7

What is a characteristic of stochastic effects related to radiation?

Probability of the effect occurring increases with the dose

Severity of the effect is proportional to the dose

Severity of the effect decreases as the dose increases

There is a threshold level of dose for the effect

6 / 7

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

Increase in genetic mutations

Random occurrence of health issues

Lowering of blood cell counts

Reduction in cancer risk

7 / 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
