Question

Exposure to even small amounts of radiation may cause

a. dna changes
b. hearing loss
c. emphysema
d. asthma

Answer 1

The answer is: a. dna changes.

Depands on radiation energy, radiotion can cause smaller or bigger DNA changes, mutations and death.

In order from highest to lowest frequency of the EM spectrum: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation and radio waves.

Gamma rays are the electromagnetic waves with the shortest wavelengths (1 pm), highest frequencies (300 EHz) and highest energy (1,24 MeV).

Gamma rays contain much more energy (most penetrating) than radio waves because they have a greater frequencies.

Answer 2

Depending on the magnitude of radiation, the effects of exposure vary too. In this case, it is assumed that the small amount of radiation here has a very high radioactivity, then definitely it can cause DNA changes. In any way, it is rare that radiation affects the lining of the lungs and can cause illnesses such as emphysema and asthma. answer is A.
