Abstract
In this study four varieties of mango fruits were irradiated with Gamma ray from Cobalt-60 source at different dose points of 50 Gy, 100 Gy, 300 Gy and 800 Gy to investigate effect of irradiation on rotting and masses. The observations were made at two different days, namely day 21 and day 14. We noticed that sample A of mango fruits irradiated with 50 Gy had 50% spoilage. sample B irradiated with 100 Gy showed only 30% of spoilage, sample C irradiated with 300 Gy showed only 20% of spoilage, sample D irradiated with 800 Gy showed 10% of spoilage. After 14 days the samples A-D show 20%, 18%, 15% and 10% loss of their mean mass and the control has lost 35% of its mass.
