FUN 1 EO: 1.27

1 / 7

What is a characteristic of stochastic effects related to radiation?

Severity of the effect decreases as the dose increases

Probability of the effect occurring increases with the dose

Severity of the effect is proportional to the dose

There is a threshold level of dose for the effect

2 / 7

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

All of the above

Genetic mutations

Radiation-induced cataract formation

Cancer development

3 / 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 vary with the dose and have a threshold

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

Non-stochastic effects always lead to cancer and genetic effects

4 / 7

Which statement is true regarding stochastic effects?

The severity of the effect increases as the dose increases

They have a threshold dose below which no effects will occur

They occur by chance and have no established threshold

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

5 / 7

Stochastic effects generally occur without:

Any chance of occurring with low exposure

A threshold level of dose

Any relation to the dose

Increasing severity with increasing dose

6 / 7

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

Genetic mutations and cataracts

Cataracts and skin burns

Skin burns and lowering of blood cell counts

Cancer and genetic mutations

7 / 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
