What does ionizing radiation sign mean?
The new symbol is a universal radiation warning symbol with the message of “Danger-Stay Away”. It is intended for IAEA Category 1, 2, and 3 sources defined as dangerous sources capable of causing death or serious injury.
Which warning symbol clearly conveys a message that there is ionizing radiation in an area it’s dangerous and that people should stay away?
trefoil symbol
The black-and-yellow trefoil symbol—long the accepted label for denoting radioactive material—is getting a com- panion. And it’s hoped that the new symbol will alert more people to the potential dangers of large sources of ioniz- ing radiation and save lives.
Is UV light ionizing or nonionizing radiation?
Non-ionizing radiation includes the spectrum of ultraviolet (UV), visible light, infrared (IR), microwave (MW), radio frequency (RF), and extremely low frequency (ELF).
How do you test for ionizing radiation?
Medical exams that use ionizing radiation include: X-rays. CT or CAT (computed tomography) scans. PET (positron emission tomography) scans.

What do u mean by non-ionizing radiation?
(non-I-uh-NY-zing RAY-dee-AY-shun) A type of low-energy radiation that does not have enough energy to remove an electron (negative particle) from an atom or molecule. Non-ionizing radiation includes visible, infrared, and ultraviolet light; microwaves; radio waves; and radiofrequency energy from cell phones.
What is the most ionizing?
Alpha particles
Alpha particles have approximately four times the mass of a proton or neutron and approximately ~8,000 times the mass of a beta particle (Figure 5.4. 1). Because of the large mass of the alpha particle, it has the highest ionizing power and the greatest ability to damage tissue.
