This phase I trial studies the side effects and best dose of total bone marrow and lymphoid irradiation when given together with chemotherapy before donor stem cell transplant in treating patients with myelodysplasticsyndrome or acute leukemia. Total marrow and lymphoid irradiation is a type of radiation therapy that targets bone marrow and blood, where the cancer is, instead of applying radiation to the whole body. Stem cell transplants use high doses of chemotherapy and radiation therapy, such as total marrow and lymphoid irradiation, to kill cancer cells, but these treatment kills normal cells as well. After chemotherapy, healthy cells from a donor are given to the patient to help the patient grow new blood cells.
