Question 1 Report
The table shows four safety precautions and the type of radiation each is said to protect against. Which row is correct?
| Safety precaution | Radiation | |
|---|---|---|
| A | wearing oven gloves | ultraviolet |
| B | standing behind a glass screen | gamma rays |
| C | wearing a lead apron | X-rays |
| D | applying sunscreen | infrared |
Answer Details
Checking each precaution against the radiation it should protect against: oven gloves protect against heat (infrared radiation and conduction), not ultraviolet; a glass screen does not meaningfully block gamma rays, which need thick lead or concrete shielding; sunscreen protects the skin from ultraviolet radiation, not infrared.
Wearing a lead apron to protect against X-rays is correct: lead is dense enough to absorb and block X-rays effectively, which is why lead aprons are used in medical and dental X-ray procedures.
The other three rows each pair a real safety precaution with the wrong type of radiation.
