1000 Rem or 10 Sieverts will almost certainly kill within a few weeks. 500 Rem or 5 Sieverts will kill about 1/2 those receiving it.
You may be referring to a wide class of radiation known as ionising radiation. Just which parts of this class that should be considered lethal to people is subject to contraversy. Please see the link.
The lethal dose of radiation is typically around 4 to 6 grays. This amount of radiation is considered to be lethal and can cause severe damage to the body's cells and tissues.
Radio waves, microwaves, infrared radiation, visible light, and ultraviolet radiation are examples of non-lethal waves to humans because they have lower energy levels that are not harmful to human tissues.
infrared radiation is invisible to humans
Radio waves, microwaves, and visible light are non-lethal to humans in normal conditions. These waves have lower energy levels compared to ionizing radiation such as X-rays and gamma rays, which can be harmful to living tissues.
Radiation is lethal to Humans, So no.

Yes, exposure to high levels of gamma radiation can be lethal. It can damage cells and tissues in the body, leading to various health effects like radiation sickness, organ failure, and even death. It is important to limit exposure to gamma radiation and take appropriate safety precautions in environments where it is present.
The scientific community has not definitively proven that the low levels of radiation emitted by cell phones are harmful to humans. However, it is recommended to limit exposure by using hands-free devices or speakerphone, and keeping the phone away from the body when not in use.
67,500 rems or 90,000 to 105,000 for German cockroaches
Like any creature, yes, they can survive a certain limit. They can withstand higher amounts of radiation than humans, but will still succumb to its effects at some point.
Fleas can transmit diseases to humans, such as typhus and plague, which can be lethal if not treated promptly. While fleas themselves are not typically lethal, the diseases they carry can pose a serious threat to human health.
Harmful frequencies to humans include ionizing radiation such as X-rays and gamma rays, as well as high-frequency electromagnetic radiation like ultraviolet and microwave radiation. To protect ourselves, we can limit exposure by using shielding materials, maintaining safe distances from radiation sources, and using protective gear like lead aprons or sunscreen.
