Kato (2004) suggested that by conducting quasi-dynamic simulations, such a concentration of rupture fronts may cause radiation of a seismic signal.
During a long stay on the moon or a flight to Mars, energetic particles from the sun or from outer space may cause radiation sickness, skin cancer, and even death.
Mammography uses X-rays which may cause radiation-induced mutations.
Hypoxia may cause radiation resistance and promote lymph-node metastasis.
However, transplanted marrow may cause the radiation victim to reject the donated tissue or develop fatal disease associated with the transplant.
Ingestion or inhalation of large amounts may cause acute radiation poisoning and death; however no human is known to have died because of inhaling or ingesting plutonium, and many people have measurable amounts of plutonium in their bodies.
These results suggest that astrocytoma cancer stem-like cells together with enhanced autophagy may cause resistance to radiation therapy/chemotherapy and that targeting the cancer stem-like cell in astrocytoma may offer a viable therapeutic approach.

The high locally achieved radiation dose, however, may cause inflammatory infiltrates and radiation necrosis more frequently than do standard treatment modalities, rendering differential diagnosis between benign reactive post-therapeutic effects and tumour recurrence more difficult.
However, radiation may cause both acute effects, which occur during radiation and in the immediate weeks and months following treatment, and late effects, which develop gradually over several months or years, on the bones and soft tissues surrounding the neck and nasopharynx [2].
