gamma rays
The extremely high energy of gamma rays allows them to penetrate just about anything. They can even pass through bones and teeth. This makes gamma rays very dangerous. They can destroy living cells, produce gene mutations, and cause cancer.
alpha particles

Non-lead shielding materials are manufactured with additives and binders mixed with attenuating heavy metals that fall into the same category of materials as lead that also absorb or block radiation. These metals may include tin (Sn), antimony (Sb), tungsten (W) bismuth (Bi) or other elements.
Staying inside will reduce your exposure to radiation.
Chemically incorporated into a polymer, gold is less poisonous than other heavy metals that also block radiation.
High levels of RF waves can cause a warming of body tissues, but the energy levels on the ground near a cell phone tower are far below the levels needed to cause this effect. So far, there is no evidence in published scientific reports that cell phone towers cause any other health problems.
300-400 meters
WCFs will, in many cases, be mounted on neighborhood streetlights or telephone poles. Draft PAWO specifies a no-exception minimum distance of 20 feet from homes, while many residents argue for 100 feet. Twenty feet is about the length of two cars!
A typical cellphone has enough power to reach a cell tower up to 45 miles away. Depending on the technology of the cellphone network, the maximum distance may be as low as 22 miles because the signal otherwise takes too long for the highly accurate timing of the cellphone protocol to work reliably.
Whenever a cell phone is used, it emits an electromagnetic radio wave, called a radio frequency, that is received by the nearest cell tower’s antenna. This allows the call to be connected to either another mobile phone or to a telephone network. It’s crazy to think all of this happens in mere seconds.

Although the FCC permits an effective radiated power (ERP) of up to 500 watts per channel (depending on the tower height), the majority of cellular or PCS cell sites in urban and suburban areas operate at an ERP of 100 watts per channel or less.
