One example of such equipment is the 360 gamma, a radiation protection belt that applies selective shielding to protect the bone marrow stored in the pelvic area as well as other radio sensitive organs in the abdominal region without hindering functional mobility. More information on bone marrow shielding can be found in the "Health Physics Radiation Safety Journal". article Waterman, Gideon; Kase, Kenneth; Orion, Itzhak; Broisman, Andrey; Milstein, Oren (September 2017). "Selective Shielding of Bone Marrow: An Approach to Protecting Humans from External Gamma Radiation". Health Physics. 113 (3): 195–208. doi:10.1097/HP.0000000000000688. PMID 28749810. S2CID 3300412., or in the Organisation for Economic Co-operation and Development (OECD) and the Nuclear Energy Agency (NEA)s 2015 report: "Occupational Radiation Protection in Severe Accident Management" (PDF). Reduction of incorporation
Where radioactive contamination is present, an elastomeric respirator, dust mask, or good hygiene practices may offer protection, depending on the nature of the contaminant. Potassium iodide (KI) tablets can reduce the risk of cancer in some situations due to slower uptake of ambient radioiodine. Although this does not protect any organ other than the thyroid gland, their effectiveness is still highly dependent on the time of ingestion, which would protect the gland for the duration of a twenty-four-hour period. They do not prevent ARS as they provide no shielding from other environmental radionuclides. Fractionation of dose
If an intentional dose is broken up into a number of smaller doses, with time allowed for recovery between irradiations, the same total dose causes less cell death.
Ichthyosis acquisita is a disorder clinically and histologically similar to ichthyosis vulgaris. : 565

Presentation
Associated conditions
The development of ichthyosis in adulthood can be a manifestation of systemic disease, and it has been described in association with malignancies, drugs, endocrine and metabolic disease, HIV, infection, and autoimmune conditions. : 494 It usually is associated with people who have Hodgkins disease but it is also occurs in people with mycosis fungoides, other malignant sarcomas, Kaposis sarcoma and visceral carcinomas. It can occur in people with leprosy, AIDS, tuberculosis, and typhoid fever. See also
