00:00:00.000 --> 00:00:03.040
So radon is naturally
occurring everywhere,

00:00:03.040 --> 00:00:06.200
and radon gas is released
when uranium slowly

00:00:06.200 --> 00:00:07.639
decays in the ground and

00:00:07.639 --> 00:00:09.940
seeps towards the
Earth's surface.

00:00:09.940 --> 00:00:12.039
It can enter homes
through cracks in

00:00:12.039 --> 00:00:13.439
the foundation and gaps

00:00:13.439 --> 00:00:15.680
around plumbing
or drainage.

00:00:15.680 --> 00:00:17.259
Because of the way we

00:00:17.259 --> 00:00:19.099
insulate and
seal our homes,

00:00:19.099 --> 00:00:20.400
radon gas can get trapped

00:00:20.400 --> 00:00:21.680
inside a building's.

00:00:21.680 --> 00:00:24.280
You can't see
or smell radon,

00:00:24.280 --> 00:00:26.679
so most people are
unaware of the buildup,

00:00:26.679 --> 00:00:29.720
and radon can spike
to dangerous levels.

00:00:29.720 --> 00:00:31.399
A radon detector
alerts you

00:00:31.399 --> 00:00:32.980
when radon
levels are high.

00:00:32.980 --> 00:00:34.399
It helps you keep track of

00:00:34.399 --> 00:00:36.180
these levels over time.

00:00:36.180 --> 00:00:37.479
Simple ventilation,

00:00:37.479 --> 00:00:40.040
like opening a
window, can help.

00:00:40.040 --> 00:00:41.980
If high radon continues

00:00:41.980 --> 00:00:44.000
even after you increase
the ventilation,

00:00:44.000 --> 00:00:45.239
you should call
a professional

00:00:45.239 --> 00:00:46.479
so they can take steps

00:00:46.479 --> 00:00:48.120
to stop radon from

00:00:48.120 --> 00:00:50.360
entering your
home for good.
