What type of x-ray is considered the most dangerous on the electromagnetic spectrum?

Therapeutic x-rays are considered the most dangerous on the electromagnetic spectrum due to their higher energy levels and longer exposure times compared to other types of x-rays. These x-rays are typically used in radiation therapy to treat cancer and can deliver significant doses of radiation to specific areas of the body. While this is crucial for destroying cancerous cells, it also increases the risk of damage to surrounding healthy tissue and cells.

The higher energy associated with therapeutic x-rays means they have a greater potential for causing ionization in biological tissues, which can lead to increased radiation-induced effects such as mutations, cellular damage, or an increased risk of developing secondary cancers.

In contrast, medical, diagnostic, and industrial x-rays are generally used in lower doses or for specific, less prolonged applications, making them less hazardous in terms of potential for immediate damage or long-term consequences.
