A direct -ray photograph of the intenstines is not generally taken by radiologists because
1
intenstines would burst an exposure to X-rays
2
the X-rays would be not pass through the intenstines
3
the X-rays will pass through the intenstines without causing a good shadow for any useful diagnosis
4
a very small exposure of X-rays causes cancer in the intenstines
