Radiation is a form of energy in waves which exists on a spectrum with low frequency radiation from radio waves as well as microwaves on the low end and which also exists on a spectrum with high frequency radiation from gamma rays as well as x rays on the high end

1. Radiation is a form of energy in waves which exists on a
spectrum with low frequency radiation from radio
waves as well as microwaves on the low end and which
also exists on a spectrum with high frequency radiation
from gamma rays as well as x rays on the high end. The
lower the frequency radiation of the waves and the
lower the exposure, the less dangerous it is but all the
radiation affects the cells in our bodies to some extent.
Some sources of the environmental radiation include
radon gas in the home, mineral potassium in the body,
radiation from outer space, radioactive compounds in
soil and building materials, etc.

2.  It is well established that the exposure to the large
amounts of radiation at once can also cause acute
sickness as well as even cancer. There are some
enzyme systems in the body which repair damages
from these low levels of background radiation but
even small levels of these radiation exposure may
impact cancer risks later in life. Some other various
sources of the radiation exposure includes abdominal
CT scan, living in Denver, mammogram, living at sea
level, chest x ray, smoking, living within 50 miles of a
nuclear power plant, dental x ray, banana, etc.

4.  Medicines can do a lot toward curing, preventing as
well as easing many ills but taking a fistful of
medicines each day creates its own set of medical
risks. The chance of having a drug interaction or a
major side effect increases if someone keeps
increasing the number of prescriptions. The use of
more medications than someone actually needs is a
concept which is also known as polypharmacy and
this does not only includes the prescription drugs but
also the dietary supplements as well as the over the
counter medications. It is very common for the
caregivers to have to keep a track of nine or more
than nine prescribed medications for each and every
person when the elderly patients transfer from the
hospitals to the nursing homes for rehabilitation.
