There are two main types of radiation: External Radiation External radiation is the most common type of radiation, typically given after lumpectomy and sometimes, mastectomy. Internal Radiation Internal radiation is a less common method of giving radiation. It is being studied for use after lumpectomy.
Gamma radiation
what describes the standard hazard marking for biological hazards
Infrared radiation is a type of electromagnetic energy
Alpha radiation
Alpha Radiation
A radio chemical hazard is a hazard where the chemicals involved emit radiation. This type of hazard is more common when dealing with fuel rods used in nuclear reactors.

Although there are many forms of "radiation" when assessing radiation hazards we usually think in terms of just three forms of radiation: alpha, beta, and gamma. Of these, alpha radiation is only a hazard if a source is inhaled or ingested - the other two are a hazard even without inhalation or ingestion. In general, external alpha radiation is not harmful since alpha particles are effectively shielded by a few centimeters of air, a piece of paper, or the thin layer of dead skin cells. On the other hand, if you inhale or ingest an alpha emitter, it can cause significant damage if the radiation is intense enough. Beta particles (electrons) are more penetrating, but still can be absorbed by a few millimeters of aluminum. Whatever harm beta radiation can cause, it doesn't have to be inhaled or ingested to do it. Gamma radiation is the most penetrating - that's the kind of radiation we usually think of using lead to shield us from. Again, gamma radiation is a hazard whether or not you inhale or ingest it.
Radiation is the only type of heat transfer that can occur through vacuum (space with no particles).
Gamma radiation
what describes the standard hazard marking for biological hazards
Actually, gamma is the ONLY type of radiation ray. Since the three types of radiation are alpha particles, beta particles, and gamma rays, and the other two are particles, technically, gamma rays are the only radiation rays. If that is not what you are looking for, then I recommend rephrasing your question.
what describes the standard hazard marking for biological hazards
Ionizing radiation is only one type of radiation. Visible light, for example, falls under the category of electromagnetic radiation. Radiation has many different detectable consequences.
Visible-- waves are the only electromagnetic waves we can see.
