It is common to see the doors of CT rooms in hospitals made of thick lead plates. So why do thick lead sheet protect the staff and patients from radiation damage? This article will explain why lead plates protect medical staff and patients from radiation exposure.

Due to the high density of the lead plate, the gap between the particles of the lead plate is small, smaller than the ultraviolet spectrum length, that is, the length of the spectrum generated by the radiation, so that the wavelength of the radiation cannot pass through the lead plate, so the lead plate can isolate the radiation.

1) Some people say that radiation is the flow of released microscopic particles.

2) All kinds of visible light, including the primary color light, as well as a variety of polychromatic light synthesized from the primary color light, then the ultraviolet spectrum will also be combined with a variety of visible light, forming a variety of coexistence of electromagnetic waves. The harm caused by ultraviolet radiation to human body, we are talking about the electromagnetic wave generated by solar radiation, the harm caused by nuclear radiation is the ultraviolet outside, that is, electromagnetic wave, not particle flow. Lead plates are commonly used in radiation protection engineering in hospitals to protect medical staff and patients from lead, a contaminant. The pollution of lead to the environment is mainly caused by the industrial and mining enterprises smelting, manufacturing and using lead products, especially the lead-containing waste water, waste gas and waste residue discharged in the process of non-ferrous metal smelting. So in the processing of lead plate, must be strict management. It is particularly important to maintain the performance of the lead sheet.

When storing lead sheets, we need to pay attention to them in order to maintain their performance for longer. There are mainly the following points:

Lead plates must not come into contact with acid or alkali solutions to prevent surface corrosion and impair their function.
