Name

Which radiation is not ionising radiation?

beta

X-ray

delta

What exposure risk do you take when working with X-ray generators ?

internal exposure

external exposure

internal and external exposure

What means ALARA in an X-ray safety context?

the obligation to protect one-self by led shields when working with X-rays

the radiation dose that is received should be as low as reasonably achievable

it is the acronym of the organisation that checks whether a laboratory fullfils the requirements of the x-ray safety rules

What is the main unit used in radiation protection?

the Becquerel

the Sievert

the Radon

Pregnant women are obliged by law to stop working with X-rays.

yes, this is true

no, this depends on the dose that is expected to be received; it is an issue that should be discussed with the doctor

no, the received doses are indeed very low

For which occupation is the average annual dose in general the highest?

diagnostic or therapeutic radiologist

baggage X-ray machine operator

aircrew

What is meant by a self-protecting X-ray machine enclosure?

the enclosure has a safety circuit to prevent the X-ray tube to become too hot and thus to avoid any fire

the enclosure has a safety circuit so that the user cannot be accidently irridiated

the enclosure has a safety circuit in order to minimise the risks that a sample becomes radioactive

What is the exposure limit for 12 running months for somebody working with X-rays, as defined by the French Labour Code?

20 mSv

20 Bq

20 Kev

Are microwaves considered to be ionizing radiation?

yes

no

this depends on the microwave power

Does one change the molecular structure of organic compounds by exposing them to X-rays?

yes

no

this depends on the radiation dose received by the sample

The effects of ionizing radiation do not depend on

the nature of the radiation

the exposured organ

the age of worker in contact with the radiation

Amongst these "tools", which one is not used to protect people against the danger of X-rays?

the X-ray safety training

the procedures for checking the safety aspects of diffractometers

medical care for people exposed to X-rays

If it smells burnt in the X-ray lab

I use the emergency stop and call immediately the X-ray safety officer

I leave the X-ray lab immediately

I try to find out what is burned

If the detector does not move anymore

I try to move it physically

I use the emergency stop and call the X-ray safety officer

I stop my measurement and call the X-ray safety officer or the engineer who is responsible for the diffractometer

If the diffractometer does not obey to the instructions sent by me by computer

I call the lab's computer guy

I reboot the computer

I call the engineer who is responsable for the X-ray diffractometer

Choose your town and laboratory

Give laboratory code (ask you radiation safety officer)
