This is Science Today. A new, lightweight and inexpensive
carbon monoxide sensor has been developed by scientists
at the Lawrence Berkeley National Laboratory. Field-testing
found these small sensors are more accurate than
the personal monitors currently on the market. Michael
Apte, a scientist in the Lab's Environmental Energy
Technologies Division says before, there was no
affordable way to accurately measure carbon monoxide
in the field.
This device actually gives you numbers for carbon
monoxide exposure. Something you could wear on your
body or you could place it in a space and it will
give you an average concentration over the period
of time that you have it on for - typically eight
hours. So it's good for measuring worker's exposure
to carbon monoxide.
It can also be placed in a residential setting to
gather average exposure rates in a home over a one-week
Carbon monoxide is very toxic. There are about nineteen
thousand poisonings every year and it makes it the
number one cause of poisoning in the United States.
