Lead clothes u kno lead can stop the raditions

Radiation covers anything traveling in rays like light. Ionizing radiation is the type to avoid. Limit the number of xrays or other medical procedures that use radiation or nuclear materials. Take fewer cross contry flights, as in the upper atmosphere you get more radiation.Don't work for a nuclear facility or live near one. Stay out of the sun, ultraviolet rays can cause skin cancer or cataracts,Don't go to uranium mines.Cosmic rays you are going to get. Stay away from xrays and nuclear. Don't live and work near high power tranmission lines.Don't worry about it unless you are working in a lab with exposure.

A lead shield. Or very thick concrete. There are not many ways to protect from radiation and don't listen to any 1950's Cold War radiation propoganda, its all untrue.

By closing the microwave door

Most protection from radiation involves lead.

Stay away from radiation. That includes the obvious radioactive elements but also X-Rays, Cosmic Rays on tops of mountains, too much sun without sun screens, too much use of cell phones, limit the number of X-Rays you allow your dentist to take to no more than once every other year. These are the easiest things for you to do.

Different types of radiation behave in a different way, so different shielding techniques are being used.

Particle radiation consists of a stream of charged or neutral particles, both charged ions and subatomic elementary particles. This includes solar wind, cosmic radiation, and neutron flux in nuclear reactors.
Alpha radiation (helium nuclei) is the easiest to shield, because the very massive alpha particles can be stopped even with a leaf of paper.
Beta radiation (electrons) is more difficult, but still a relatively thin layer of aluminum can usually do the job. However, in cases where high energy beta particles are emitted (e.g. 32P), the Bremsstrahlung produced by shielding this radiation with the normally used materials is itself dangerous; in such cases, shielding must be accomplished with low density materials, e.g. Plexiglas, acrylic, Lucite, plastic, wood, or water [1].
In case of Beta+ radiation (positrons) the gamma radiation from the annihilation reaction poses additional concern.
Neutron radiation is not as readily absorbed as charged particle radiation. Neutrons are absorbed by nuclei of atoms in a nuclear reaction (which often leads to emission of gamma photons, causing additional shielding concerns), but fast neutrons have first to be slowed down (moderated) to slower speeds, by inelastic collisions with heavy nuclei or by elastic collisions with light ones. Large mass of hydrogen-rich material, eg. water (or concrete, which contain a lot of chemically-bound water), polyethylene, or paraffin wax is commonly used. It can be further combined with boron for more efficient absorption of the thermal neutrons.
Cosmic radiation is not a common concern, as the Earth's atmosphere absorbs it and the magnetosphere acts as a shield, but it poses a problem for satellites and astronauts. While satellite electronics can be radiation hardened, astronauts can't, so they have to be shielded. Because weight is a premium on space technology, methods alternative to absorption are being proposed, eg. shielding using superconductor electromagnets.[2][3] Aircrews and frequent flyers are at a slight risk too.
Electromagnetic radiation consists of emissions of electromagnetic waves, the properties of which depend on the wavelength.
X-ray and gamma radiation are best absorbed by atoms with heavy nuclei; the heavier the nucleus, the better the absorption. In some special applications, depleted uranium is used, but lead is much more common. Barium sulfate is used in some applications too. When cheapness is important, almost any material can be used, but it must be far thicker. One standard design practice is to measure the halving thickness of a material, the thickness that reduces gamma or x-ray radiation by half. When multiple thicknesses are built, the shielding multiplies. For example, a practical shield in a fallout shelter is ten halving-thicknesses of packed dirt. This reduces gamma rays by a factor of 1/1024, which is 1/2 multiplied by itself ten times. This multiplies out to 90 cm (3 ft) of dirt. Shields that reduce gamma ray intensity by 50% (1/2) include (see Kearney, ref):
9 cm (3.6 inches) of packed dirt or
6 cm (2.4 inches) of concrete,
1 cm (0.4 inches) of lead,
0.2 cm (0.08 inches) of depleted uranium,
150 m (500 ft) of air.

Ultraviolet radiation is absorbed in organic molecules of certain structures, being the active ingredients of sunscreens. Anything that stops ordinary low-energetic radiation will do the job too. The ozone layer absorbs UV radiation, but its depletion considerably lowers its effectivity especially in northern and southern areas of the globe.

well there are several types of radiaton but most radiation canot easily pass through lead and reinforced concrete

make sure the microwave has adequate shielding or wear a lead suit at all times
