Answer:
A. cancer therapy;
B. detect and locate cancer;
C. genetic engineering;
F. pain relief.
Explanation:
Radiations are of great use for cancer treatment and detection. Radiotherapy/ radiation therapy is a type of medical application in which a tumor/ cancer tissue is exposed to high energy radiations which kill these cancerous cells and restrict them from growing further. Treating the painful cancerous tissue/cells with radiations causes relief in our body and we feel better after such treatment.
Apart from this, if we have pain in our bones and we expose them to certain radiations, it works as a pain reliever in our body and helps us in swift movement.
Radiations are widely used in genetic engineering for generating mutations. By inducing mutations in a hereditary unit (DNA or chromosome), we can improve the traits/quality of some plants and animals.
