In brief: Yes

1000 units is not excessive as most multivitamins contain 5000 units.
Antioxidants may help you tolerate radiation side effects. A nutritional purple ENT that is helpful is a medicinal mushroom blend such as matake-d.

In brief: No standard answer

This is an area of controversy, and there are no established safety guidelines.
In general, radiation oncologists recommend that any doses greater than typically recommended by the usda (http://fnic.Nal.Usda.Gov/dietary-guidance/dietary-reference-intakes/dri-tables) should be avoided. A daily multi-vitamin is likely completely safe. Dietary intake through whole foods is the recommended route.
