What may be thought of as a form of identification in CBRNE?
What form of ionizing radiation can penetrate deeply into tissue

Why are cancer cells more sensitive to radiation than nerve cells?
Because Prof.Kodjo thought so
All electromagnetic radiation can travel thought empty space and travels at the same speed?
true
Is everyhting made of elements?
Not everything: electromagnetic radiation, beta radiation, gamma radiation, particle beams etc. are not formed from elements.
What is the effect of LD50 30 radiation on human skin?
LD50/30 radiation refers to the dose of radiation required to kill (LD=Lethal Dose) 50% of the test cohort within 30 days. Its normally specified for a particular species, rats, rabbits etc and is thought to be about 3-4 Sieverts in humans. The wikipedia article "Radiation Poisoning" has a table of effects of increasing radiation on humans. Note that at 3-4 Sv there are no skin effects if it is whole body exposure. If it is localised exposure then there will be radiation burns followed by erythema.
Light produced when a black hole decays is called?
A type of weak radiation thought to be present due to quantum effects near a black hole's event horizon is often called Hawking radiation, after the scientist who proposed it, Professor Stephen Hawking.
How heat energy transferred by radiation?
Heat is transferred through air and space as electromagnetic radiation. A daily example is the infrared (the heat lamp), whose spectrum is just about or below the visible light frequencies, and infrared radiation can be thought of as traveling but invisible photons (light is a form of electromagnetic radiation) of low energies. In general, all objects emit thermal radiation through oscillation of charge particles in matters, even when the objects are near zero degree Kelvin.
What term is used to describe the fact that electromagnetic radiation can be thought of as either a continuous wave or as a stream of individual packets of energy?
wave-particle duality
Did the Allies know about the harm of the Atomic bomb?
The devastation of the Atomic Bomb was known but never thought to be needed twice. There was little known knowledge of the effects of radiation.
How are energy and electromagnetic radiation related?
Electromagnetic radiation is one way that energy can be transfered across a distance. EM radiation can be thought of as packets of wave, each called a photon. A photon has a certain amount of energy, which can be found using the formula "E = hf", where 'f' is the frequency of the light, and 'h' is plancks constant (h = 6.626×10−34 Js).
Is alpha radiation a ionization radiation?
Yes, alpha radiation is an ionizing radiation.
