Question

The quantity of scattered radiation reaching the IR can be reduced through the use of

1. an air gap
2. a stationary grid

Answer 1

An air gap and a stationary grid can be used to reduce the quantity of scattered radiation reaching the IR.

Step-by-step explanation:

The quantity of scattered radiation reaching the IR can be reduced through the use of an air gap and a stationary grid. An air gap is a space between the radiation source and the IR detector, which helps to block or reduce the amount of scattered radiation that reaches the detector. A stationary grid, on the other hand, is a device made up of lead strips that are arranged in a crisscross pattern. It is placed between the radiation source and the IR detector and helps to absorb and block scattered radiation.
