Q1.Food irradiation is a process that exposes food to radiation. Irradiation can be used to kill the bacteria that cause food poisoning or to slow down the ripening of fresh fruit and
vegetables. Frozen foods and food inside packaging can also be irradiated.
(a) The table gives information about five radioactive isotopes.

Isotope Half-life Radiation emitted
Caesium-134 2.1 years beta
Cobalt-60 5.3 years gamma
Curium-242 160 days alpha
Strontium-90 28 years beta
Technetium-
99

6 hours gamma

Which of these radioactive isotopes would be most suitable for irradiating
food?

Explain the reasons for your choice.

the answer is b i think

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

joke:

h o h o hope you have a merry christmas!

there are no components of a physical goal mentioned on the list of choices that you've provided.
