We speak of irradiation by external exposure to ionizing radiation, when a person is exposed from the outside by the ionizing radiation emitted by a radioactive source located in its vicinity (like the waste of the nuclear power stations or the remains of the explosion nuclear energy such as Hiroshima and Nagasaki). In this case, exposure ceases when the source of radioactivity is moved away from the person or if a screen (shielding) is interposed between the person and the source.
While a contamination by an internal exposure to radioactive particles, that is to say when radioactive elements have penetrated inside the organism, as in the case of ingestion e radioactive product as the iodine 131 in a diagnostic or therapeutic purpose.

_____ refers to the loss of protein three-dimensional structure when temperature or ph is altered.
UNO [17]

Denaturation refers to the loss of protein three-dimensional structure when temperature or pH is altered.

Denaturation is the phenomenon in which the tertiary structure of the protein is broken down due to the breakage of bonds between the amino acids of proteins. This breaking of bonds occurs due to the change in pH or temperature from the normal at which the protein remained active.

Three-dimensional structure of the protein is its form in which the protein remains active and functional. It is generally tertiary structure of protein. This active tertiary structure is decided by the sequence of amino acids in the primary structure of protein, where the protein exists as a linear chain.
